The only thing I could add to that is the Sixers’ eyes got bigger than their wallet or their common sense. Their eye was on the prize. Like the Spurs, they needed an established big man after they let Samuel Dalembert go. Unlike the Spurs, they didn’t, as you concluded, analyze or screen out the possibilities of reoccurring knees problems or personality issues. The Spurs are still in need for that big but they’re doing just fine without one, finding ways to mend that problem with the assets they do have. That ability comes from stabilized coaching which might account for the Spurs having 4 championships, a coach who is presently the longer sitting coach in the league and are the model franchise for efficiency in all sports.
I'm great at multi-tasking -- I can waste time, be unproductive, and procrastinate all at once. Ain't life grand!!
