While it is true that the biggest obstacle to Iverson becoming a 6th man would be his acceptance of the role, even if he did accept that could he even be a 6th man? The answer is simply no. Changing from a star player to a role player is one of the most difficult transitions for a basketball player. Shaquille O'Neal is also struggling with this transition. Its difficult because the strongest parts of your game are no longer all that strong and you must find new ways to contribute. Jason Kidd and Ray Allen are some of the few guys currently who have been able to make this transition.
The transition for Allen Iverson though looks nearly impossible. At his best, Iverson was a penetrating guard who created points for himself by finding small creases in a defense for a lay up or going to the line. When defenses overplayed his penetration he could dump off to an open shooter for more offense. Its really a shame he didn't have much talent around him in his prime because when he was at his best he was as lethal a player as this league has seen in the post-Jordan era. However, he never could shoot. Sure, every once in a while he'd have a game where he'd find a hot streak but these were few and far between. Iverson's ability to drive and take the relentless beating he once took is no longer there. He can't create for himself or for others anymore. The only way he can legitimately find himself playing time is to be able to defend or shoot well. Iverson has never been able to do either of these things. He has no way to become a role player and is no longer the instant offense he once was. Quite frankly, Allen Iverson had reached the end of his glorious career and while it is a shame that this is the way it will end, it wasn't going to end in any prettier of a fashion.
