Stop
So you seriously think that was entirely on Diarra? I'll grant that Diarra has a tendency to try to do to much (especially when no one else wants the ball). But he was put in a position to fail.
Diarra was in the position of being the outlet pass for Martin. Should he have been the outlet pass? No, we all know he's not that offensively capable.
But when Sam Martin can't get 10 feet up the court, somebody needs to handle the ball.
