I am a Dorsett fan.
His turnovers suck, but he can learn to tuck the ball as he's making these big plays (both turnovers were x-plays). And he blocks. He is in nearly every highlight even when he's not making the play because he's always first guy down field blocking.
I divide bad plays into two categories: correctable and not correctable. Dorsett is a coachable kid and can learn how to run with the ball and not lose it.
