They'll attempt a pass even if it really isn't there if an older player calls for it. I can recall T. Reimer having a lot of turnovers like that as Freshman. Jackie was the culprit a few times Monday. On some the pass was just inaccurate. Also B. Turner and J. Sheppard missed enough bunnies to make things appear even worse.
Penn also had a very good zone. Mabrey will help with that. But I think it's going to be a high turnover team because of style. They're going to push the ball.
