The NYTimes pretty much sums it up for me.
Iverson is too old to be viewed as a core player for the future. He has been a source of controversy throughout his career, even when he was leading the Philadelphia 76ers to the finals in 2001. His Grizzlies tenure lasted just three games, primarily because he bristled at playing a bench role — the same issue that soured his relationship with the Detroit Pistons last season.
For all of the passion he shows in games, Iverson is notorious for poor work habits and a sometimes-reckless lifestyle, which could pose concerns with a young team. The Knicks cut ties with Stephon Marbury last season because he was viewed as a poor influence.
On a more fundamental level, Iverson could inhibit the growth of the Knicks’ prospects. Danilo Gallinari, Wilson Chandler, Toney Douglas and Jordan Hill need shots and playing time. Iverson would take minutes away from Douglas and shots from everybody.
