i think it's just a confidence issue. frank anally raped will and will hasn't been able to recover. hopefully he does better under oscar the panda bear.
imo, what made him decent his freshman year was he knocked down open j's and he hustled for loose balls. when he was asked to do more in the offense, he struggled, frank pressed, will crashed, frank pressed harder, will crashed farther, and things went from there.
there's no way that kid should ever be asked to be more than a spot up shooter and a decent defender at this level.
