It has been a struggle to understand what Fultz is going through. Last week, a talent evaluator, who I trust impeccably and works as hard at scouting players as anyone I know, told me some of Fultz’s challenges have caused him pause. He’s now re-examining the way he evaluates players’ confidence because he believes that has also been an issue for Fultz. Whether the Fultz mystery has now been solved or not is to be determined. But it has certainly knocked the Sixers for a loop, they have been at a loss on this one for more than a year. No one saw all this coming, not even the Celtics when they traded out of the No. 1 pick and never identified a shoulder issue when they evaluated him. This was another scenario that had no tab in the manual.
