Those two had some outstanding blocks, and Cochran was blocking downfield as well. A lot of the credit goes to AJ himself. Three EIU players could have made the tackle, but didn't because AJ blew by them:
1. The left DE/OLB on the end of the line for EIU went too deep following Sprague, and left a gaping hole when McCray blocked the DT down. If he makes the play, it's probably a 1-2 yard gain.
2. Meanwhile Pruehs was downfield to block the MLB, and wasn't able to do more than just bump him. It didn't matter because AJ just blew the MLB. If he was able to make the tackle, it was a 7 yard gain.
3. Mangen was downfield to block the safety, but never really got it done. AJ blew the safety, too. If the Safety makes the tackle, probably 12 yard gain.
I suppose you could also say that the corner who overtook AJ at the end also had a chance to make the tackle, but he chose not to even try to make a tackle, and instead tried to strip the ball, and ended up just looking silly.
