That could’ve gone either way. Dumb to point to the hold when these others happened as well. I’m sure there were more but these stood out to me:

Phantom facemask - obviously not a penalty
Late hit out of bounds on Retzlaff - was “late” but rather tame in my opinion
Late hit on Rose - good call by definition but tame
PI or defensive hold on byu (Collins?) in 1st half - about the same as hold at the end

A lot of these could’ve gone either way and are quick judgement calls or split second decisions. BYU still had to drive down and make the kick.
