The Iverson Gap: Why Valuing Players Is Even Harder Than You Think

Posted: Updated:

The value of Allen Iverson is one of the most contentious topics in the world of basketball statistics. HuffPost's own Dave Berri is well known for thinking that Iverson is heavily overrated, and is decidedly unenthusiastic about his return to the Philadelphia 76ers. Other statisticians have publicly disagreed. There's some great back-and-forth about this issue, and reading more about Iverson's case provides a great introduction into advanced basketball metrics.

But as complicated as Iverson's value already was, his return to Philly adds yet another dimension to the debate.

Iverson's court presence during his debut wasn't bad, but it was hardly dominating -- he scored 11 points on 4-11 shooting and dished out six assists. But the most important number was 20,664 -- the sellout crowd that watched him Monday night. Philly's average home attendance before Monday's game was 11,966. That difference is over 40% of the stadium's seats. If those seats averaged the same price as the Wachovia Center's overall average, then Philly made around $350,000 more than average from ticket prices alone -- in a single night.

Granted, it's unlikely that Iverson's presence will result in a continued attendance spike unless the 76ers start to win again. But Iverson has a non-guaranteed contract at the veteran's minimum, and the 76ers paid for 35% of it from just ticket sales in one night. It's possible that when we figure in additional merchandise sales and in-game purchases, Philly has already paid for his deal in under a week. They've capitalized on the fact that Iverson was far more valuable to them than he would have been to any other organization.

You might notice that I left Iverson's actual basketball value as an afterthought. That's because it is. As of this writing, John Hollinger is giving the 5-18 Sixers a 10.6% chance of making the playoffs. I don't like those odds.

The truth is that the traditional currency of a player's value, the win, is fairly unimportant in a situation like this. If Iverson is interfering with the development of future players, that's one thing. But do you think fans care about the difference between a 23-win team and a 25-win team? Wins matter to the bottom line primarily when playoff contention and seed is at stake. And we can't forget the possibility that 76ers brass could reinvest all this cash flow into meaningfully good players.

This isn't an issue that ends with Iverson. The gap between a player's perceived value and his "actual" value has real consequences. Here's an example from another sport: Derek Jeter's fielding, a topic even more contentious than Iverson's value. Scouts tend to rate Jeter's fielding as above average, while statisticians usually put it near the bottom of the barrel (except for 2009, where he was universally considered above average). At its largest point, the gap between these two views could be as many as three or four wins -- $15-20 million in free agent dollars, according to Fangraphs' system.

The reality is that this issue isn't really that important when we only talk about revenue. Jeter is the most marketable player in the game of baseball, and his signature jump-and-throw is an indelible part of his image. And that's just it -- the image of his fielding is what drives revenue more than its actual quality. Sure, if Jeter's fielding is actually terrible, the Yankees will lose a few more games and lose out on some revenue. But the idea that Jeter's fielding is worth $15-20 million less is a big stretch.

All this is to say that considering a player's marketability hand-in-hand with his production is going to be a big step in sports analysis. I'm sure that teams are doing it, but the media and the statistical community tend to keep business and production separate. By combining the two, we can close the Iverson Gap and create a comprehensive figure for a player's value -- far from including every intangible, sure, but a huge step nonetheless.
