Since when has Iverson put fans in the seats?
He drew some more at first in Denver. But their attendence wasn't any different with Billups. I think winning drives attendence more than anything.
I agree, winning is the ultimate method of getting fans in the seats. Although star power helps as well. And I'm not so sure that Nate Robinson at the helm vastly increases NY's immediate chances at winning more and subsequently putting fans in the seats. Also, Iverson has shown throughout his career to marginally increase attendance, although not in Detroit. However, he has dramatically increased road attendance for his teams (though this doesn't help the NY franchise) and increased national exposure on television.
Both Denver and Detroit have recently added Iverson to their respective teams. Here is what happened to home attendance before and after Iverson arrived (data taken from ESPN.com):
First, here is season home attendence for Denver:
2005-06: 702,645
2006-07: 706,437 (year Iverson arrived)
2007-08: 711, 962
2008-09: 706,165 (year Iverson departed)
And here is Detroit:
2007-08: 905, 116 (team is at capacity)
2008-09: 896, 971 (with Iverson team is not at capacity)
All in all, there is some benefit to attendance when bringing in a star player. There's always more excitement when a star player joins a new team. Iverson in NY is a great marketing boost as well.
