I'm not a huge AJ fan. But some people are delusional about him.
He was an average point guard, who worked his ass off and had a lot of heart.
I don't care about the "clinching shot" or much other on the court stuff, but people should note that he's the Spurs all-time assist leader.
Every player who played on the Spurs in 99 will tell you that he was the guts and the drive of that team. Give Elie his due, of course, but people in the organization will name AJ first.
The Spurs organization respects him tremendously and he would probably be an assistant coach here, but Pop talked to him and they decided that Dallas would have better room for advancement.
Every organization decides what their criteria is for retiring a jersey. Two years ago it was said by several people (Pop etc) that without a doubt AJ's number would be going up. It wasn't even a question within the organization.
