From what I've read on this issue, there were a couple other teams, besides the Spurs, who voiced their interest in Johnson during that suspension. I'm thinking Van Gundy took another look at Johnson's practice habits and regrouped due to the immediate interest throughout the league. I would have to pitch my hat in the pile along with yours, MrJ, regarding Johnson. He's got a lot of upside and I'm sure he'd come around to Pop's way of coaching to get the most out of his potential.
I'm great at multi-tasking -- I can waste time, be unproductive, and procrastinate all at once. Ain't life grand!!
