In my opinion, when he's not gassed, Jasper gets great push. He had hands in his facemask and was about to sack the quarterback on the Williams interception.
That being said, he has trouble disengaging from blocks and got winded on the long Bears drive. Once he was obviously tired, he was slow to react to the ball.
But Troup had problems using his hands last year. Now look at him this year.
Also, Kellen Heard looked way better than I thought he would. I especially liked it when both he and Jasper were lined up together
