The shoulder soreness strikes me as a nice way to explain away something more embarrassing --- he's shook. The NBA has completely gotten into his head. He shot from outside constantly at Washington (or Washington St.) with stadiums 1/5th full and television on Pac12 After Dark App.
Every innuendo and indication was there; but the talent was enough to hope it away.
I don't know if I agree with this. Remember - Fultz played against Ball and UCLA, and then sat the name game because of "knee soreness".
At that point, he was listed as day-to-day.
He missed the next game, played in the next two, and then didn't play for the season.
The most interesting thing about his knee injury was that no one really ever knew when he suffered the knee injury. Also, for the six to eight weeks, no one really knew the severity of it.
To me, all of the shooting mechanics notwithstanding, since that UCLA game on February 4trh, he's played 68 minutes of college ball (two games against AZ and AZ State); 64 minutes in the Summer League before being shut down after coming down on someone's foot; 47 minutes of preseason action; and 59 minutes of NBA time.
During this time, he's missed multiple games; he apparently has problems lifting his arm above his head; and is batting his mysterious shoulder problem plus his right knee is sore again.
As with respect to the shoulder and knee, no one's ever been able to see anything that would have caused on injury.
So it doesn't seem like he's shook from being in the NBA; there seems to be something deeper going on because it seems like it's a carryover from college.
