I've been banging this drum for a while but;
I reckon CBS knew. If I'd be a betting man, I'd say this is why he was sat down a lot whilst fans were complaining of him not getting minutes.
We also saw him quite often pick up the ball after getting into the key, being stop at the middle of the freethrow line, ball in hand, looking for an out.
Whenever he gets pressured, he has issues.
.edit: so here's to beating my own drum 
The problem with Pritchard is some teams have found out his weakness; press him.
Watch next game. It's why he got yanked here too.
Under pressure, he struggles to create. Which is fair enough.
