1. Intentional grounding - QB was in the tackle box under pressure and there wasn't an eligibility receiver with reasonable distance of where the ball landed. This was called in the Utah game last night.
2. Pass interference - Chase was wearing two ASU players as he went back for the catch.
3. Horse-collar tackle - ASU guy pulled chase down by the back of his collar. This was called in Colorado game, when it wasn't a horse-collar.

I am sure there are a couple calls that could have been made during the delay of clearing the fans off the field.
