BYU called upon Mitchell to fill the void. He was tremendous in his debut as a starter. He didn't allow a single pressure on the night against one of the better defensive lines that BYU will see this season. It was unexpected and came out of left field, but Mitchell might be a guy that earned himself a starting position for the rest of the season.

This was from that 247 article. He looked good to me. I’m not an OL expert though, maybe Hans will have a different opinion.
