Utah's #25 commits Def. PI before Matthews pulls him down (obvious Offen. PI).
Watch the attached video at 7:55 - #25 has Matthews' sleeve and is yanking on it - D. PI.
Soon after, he starts driving him - literally shoving him towards the sideline - D. PI.
AFTER all of that, he starts falling and Matthews grabs on and pulls him with him - Off. PI.
Honestly, if we get it and have one more shot, nothing changes. That is not THE play to be upset about, IMO. Plus, if it is any consolation, Hill's throw could NOT have been any better. To hit a receiver on the stomach as is lying down - talk about accuracy and anticipation!
