Nothing in Particular

Bernhard Riemann did too much. In other news, I did find this movie to be good.

Why D. Wade is MVP, Part II

And from Bill Simmons, the Sports Guy:

John Hollinger stole my thunder here. Originally I wrote a longer section in this spot about how Dwyane Wade was the 2006 MVP -- how it wasn't even really that close, how he's the best two-way player in the league; how he's been scoring 33 a game and shooting 56 percent from the field for the past two months; how he's the one star in the league who can completely turn a game around in about 90 seconds; how he got over an early season funk of taking bad shots and makes the right decisions nearly all the time; how he's probably the toughest two-guard since the late-'90s MJ; how he's the most efficient superstar since the early-'90s MJ; how he's been on a mission since he didn't win the MVP at the All-Star Game; how he has a knack for raising his game when it matters -- and then Hollinger blew this same premise into an entire column. Beat me by one day. If it happens again, I'm going to have him killed.

Here's the point: Miami is 20-4 over its past 24 games, mainly because of Dwyane Wade. I see them continuing to get better and better. Why? Because he keeps getting better and better. After MJ retired, did you ever think you would see another guard average 30-35 points a night, rack up another six rebounds and six assists per game, play world-class defense and shoot 55 percent from the field? Well, it's happening.

Why D. Wade is MVP

This is a piece by John Hollinger on why Wade is MVP.

Sometimes, we tend not to notice the things that are right there in front of our faces. Take the NBA's MVP race, for instance. In one corner, we have the players who are compiling prolific numbers, but for teams that have been inconsistent: LeBron James, Kobe Bryant, Allen Iverson. In the other corner, we have players who don't look like a stereotypical MVP statistically, but whose teams have enjoyed great success: Steve Nash, Chauncey Billups, Tony Parker, Dirk Nowitzki.

Dwyane Wade
Forget Shaq for a second. Dwyane Wade is the man, too.

And then, somehow largely omitted from the discussion, we have the one guy who is performing at an absurdly high level and doing it on a contending team: Dwyane Wade. Yet we've hardly heard a peep about his being the league's Most Valuable Player.

Everyone realizes he's a great player, obviously. But I'm not sure people realize just how great he has been this year. Wade ranks "only" fifth in scoring, so the tendency is to think he hasn't been on par with players like Bryant, James and Iverson offensively. Yet because Wade is so much more efficient and is such a good passer, he's actually been the most productive offensive player of the bunch.

For starters, Wade shoots 50.2 percent from the floor, the only player in the league's top eight in scoring to hit more than half of his shots. Additionally, he attempts 11.1 free throws per game -- only LeBron gets to the line more -- and drains 77.8 percent of them. As a result, his true shooting percentage (his shooting percentage adjusted for 3-pointers and foul shots) is 58.3 percent, which comfortably tops that of James, Iverson and Bryant and ranks even with Nowitzki's.

Second, Wade is far better at creating opportunities for his teammates. Fully 20 percent of the possessions he uses end with an assist, nearly double the rate of Bryant (11.9) and Nowitzki (10.4) and far ahead of Iverson and James, as well. As an added plus, he's also a better offensive rebounder than those four, which helps get back the possessions he loses because of his slightly higher turnover ratio.

As a result, Wade is on top of the charts in player efficiency rating, my measure of a player's per-minute statistical production, and it's not because of his defensive rebounding or blocks or steals -- it's because he's been a more productive offensive player than anybody in the league, even Kobe Bryant.

Wade is probably the best defender of the MVP candidates -- the only other one who can make a good argument is Kobe. Although no player of this caliber is asked to be a defensive stopper full-time, Wade was a second-team All-Defense selection a year ago and has performed well again this season. In fact, the Heat give up two fewer points per 48 minutes when Wade is on the floor -- even though his backup, Shandon Anderson, is in the league only because of his defense. More amazingly, Wade and Tony Parker are the only MVP candidates who can say this -- the teams of Bryant, Nash, Nowitzki, Billups, James, Iverson and Elton Brand all give up more points when they're on the court than when they're off it.

But a lot of people still won't vote for Wade, because of the "Where would they be without him?" factor. Their argument goes something like this: The Suns without Nash, or the Mavs without Nowitzki, or the Lakers without Bryant, would be much worse off than the Heat without Wade. Miami, after all, still has Shaq, while the other clubs lack another star of similar caliber.

I've got news for you: The numbers say they're horribly mistaken. Miami without Wade this season has been absolutely horrendous. It's a bit misleading to look at the Heat's record when he doesn't play, since Miami is 2-1. Instead, look at the games themselves. Miami's two wins without Wade came against perennial doormats Charlotte and Atlanta, by a combined total of three points. And the one loss? A 111-93 thrashing by Phoenix in which the Heat gave up 47 points in the first quarter.

But fortunately, we have much more to look at than those three games -- we have Miami's entire season to digest. And based on those numbers, Wade has as much positive impact on his team as any other player in the league. Thanks to 82games.com (again) we can see how the Heat have performed with Wade on and off the court, as well as how the other MVP contenders have done.

And in this analysis, Wade is far, far more valuable to the Heat than Nash, Nowitzki, Parker, Billups and Bryant are to their clubs. With Wade off the floor, the Heat have been outscored by an eye-popping 8.8 points per 48 minutes. To put this in perspective, a team getting outscored by that amount would normally go about 15-67.

Additionally, no other Miami player -- not even Shaq -- has an impact anywhere close to this. Even when O'Neal is off the court, the Heat outscore their opponents by 2.9 points per game -- in fact, with any other player off the court, Miami still outscores its opponents. But without Wade, they suddenly morph into the 2004-05 Bobcats. Only one other player -- LeBron James -- is even close to Wade in this category, and in LeBron's case it's as much a condemnation of the Ira Newble/Luke Jackson contingent as it is a stamp of his own quality.

So we have a compelling case thus far that Wade has been immensely valuable this season. But I know what argument comes next: Wade can't be the MVP because the Heat is "Shaq's team," right?

Consider Wade's scintillating effort against Detroit, for instance, when he scored Miami's final 17 points, including the game-winner with 2.3 seconds left, for one of their most important wins of the season. Down the stretch of that game, as in most Heat games this season, it was Wade and not Shaq who was Miami's go-to guy.

Certainly, that perception seems to be killing Wade's chances right now. That notion was mildly annoying a year ago, when Wade played far more minutes than Shaq and was nearly as effective but got zero MVP votes to O'Neal's 58. But this year it's a preposterous proposition.

Unfortunately, we in the media probably aren't helping. Shaq is the most famous guy on the team and certainly the most loquacious, so he's our go-to guy anytime we need a quote. And if he's the one who always has his face in the mike, it only galvanizes our perception that it's "his" team. (Actually, it's Mickey Arison's team, but let's not get technical.)

Even Washington coach Eddie Jordan, whose team Wade has repeatedly shredded to pieces over the past 12 months, succumbed to the idea recently. "I'll say it's still Shaq's team," he said after a recent loss in which Wade burned him for 40. "I think he is the senior guy who has won the championships. He allows Wade to do his thing late in games, but I'd say it is Shaq's team."

The second part of Jordan's statement is the most important, because it's so widely believed. Because players like Damon Jones and Udonis Haslem had career years playing alongside Shaq a season ago, many folks believe that Shaq's arrival is a tide which lifts all boats.

Wade with and without Shaq, past two seasons

Without With
Games 28 110
FG % 48.9 49.4
Pts/40 min 28.6 26.0
Reb/40 min 6.8 7.1
Ast/40 min 6.1 5.6

But in Wade's case that's not necessarily true. He played much better last season in games in which Shaq wasn't in the lineup, and while that trend hasn't held up this year, the overall picture from Wade's two seasons with O'Neal doesn't show a strong impact by Shaq. Wade has played 28 games without O'Neal in the past two years (including two playoff games last season), and in those contests he's scored more while shooting a slightly lower percentage (see chart).

That is exactly what we'd expect -- a higher scoring average because he's getting more touches, and a lower shooting percentage because he's getting more attention from the defense. Once you compare the two numbers, the idea that Wade needs Shaq in order to play at this exalted level doesn't hold water.

This should be obvious if you think about it. While face-up shooters like Jones, Haslem and Christian Laettner last season benefited from all the attention Shaq got in the paint, it actually hurt Wade. Wade's game is all about driving to the rim with his blazing quickness, and there's a lot less room for him to do his thing with the Big Fella (and whatever 300-pound oaf is matched up against him) taking up so much room in the middle.

So in looking at Wade's season, let's quickly sum things up:

• He's been the best player in the league statistically, as shown by his No. 1 PER.
• He's arguably had the greatest defensive impact of any MVP contender.
• His team has been massively worse when he's off the court.
• He's the only MVP candidate who is both putting up monstrous numbers and playing on a contender.

If I made a case based on just one of these factors, it wouldn't be terribly convincing -- there are many different ways to evaluate players, and often they can give you very different answers about who is the best. But when all the indicators point in the same direction, it gets pretty tough to ignore.

And let's face it: It was plain to see if we looked. Wade has been right in front of our eyes all season, but because his team isn't an unexpected surprise, and we already knew he was a star, we've been taking his tremendous season for granted.

For most of the season, that's blinded us to the fact that he's become the best player in the league and is far more deserving of the MVP award than any of the other candidates thus far anointed. Fortunately, it's not too late to rectify the mistake. We may not think of the Heat as "his" team, but for Dwyane Wade, this season certainly should be "his" MVP year.

The Effect of Market Experience in Evaluating Prospect Theory

This is an interesting paper dealing with Prospect Theory vs. Neoclassical Economics. List basically argues that prospect theory is a better description of newbies, while experienced market-players are more like the rational-bums that neoclassicals like.

Anyway, here is the abstract:

"Neoclassical theory postulates that preferences between two goods are independent of the consumer's current entitlements. Several experimental studies have recently provided strong evidence that this basic independence assumption, which is used in most theoretical and applied economic models to assess the operation of markets, is rarely appropriate. These results, which clearly contradict closely held economic doctrines, have led some influential commentators to call for an entirely new economic paradigm to displace conventional neoclassical theory e.g., prospect theory, which invokes psychological effects. This paper pits neoclassical theory against prospect theory by investigating three clean tests of the competing hypotheses. In all three cases, the data, which are drawn from nearly 500 subjects actively participating in a well-functioning marketplace, suggest that prospect theory adequately organizes behavior among inexperienced consumers, whereas consumers with intense market experience behave largely in accordance with neoclassical predictions. The pattern of results indicates that learning primarily occurs on the sell side of the market: agents with intense market experience are more willing to part with their entitlements than lesser-experienced agents."
