Have there been two teams that have retired the same players number? I think the Celtics (and Timberwolves) should retire KG's number.
I can't remember a player having as significant of an impact on the Celtics as KG had, since Larry Bird. I still believe KG should have easily been name the MVP in the 2007/2008 season, over Kobe. I also believe that the Celtics win 3 titles in a row, if it wasn't for KG's knee injury that he suffered in Utah in the 2008/2009 season. Numbers alone couldn't define his impact. Naturally, Pierce and Allen also had significant impacts, but the addition of Garnett raised everyone's game/ability/expectation to the nth degree.
