Yes, there was some contact. But it wasn't a PI. As others have said, Mitch beat 22 because he was bigger, and that's it.
You Aggie fans really are kind of silly, you know that? You strain at a gnat, trying to convince yourselves that you were robbed. It happens like clockwork--every single time BYU plays you. Every time there's some invented moral outrage too. The better team won, and did it handily.
