At some point, the entire line gave up on getting an aggressive pass rush. It opened up the running lanes and then when Utah crashed down, he kept it.

If you replace Blake with a different player, I still think BYU wins that game. If you replace Hall, who knows? It’s a completely different game at that point. There wasn’t another BYU offensive player who generated anything else on his own without Hall’s help. YAC wasn’t special and RBs benefited indirectly.
