My observations on Purdue:
Moore is a playmaker. Ability to take it to the house every time he touches the ball.
Used 2 QBs. Sindelar threw 3 picks, might have earned him QB2 duties.
Defense is young, but plays aggressive/fast. Lone returning DLineman cost them the game with an unnecessary roughness on a 3rd down stop that would have given Purdue the chance to win on final drive.
Northwestern:
Also used 2 QBs, not sure if Thorsen is 100% yet or not.
Running backs seemed to have huge holes to run through, may be young D.
Scored 21 points off of 3 turnovers-x-factor.
