Can’t he just put a defender or two more in the box to stop simple runs, or get the lbs up a bit closer to the los? He thinks we still have Tonga in there to bail him out.
Run defense alignment is a big problem. You can’t give up 4-6 yard gains on simple handoffs against an inferior team. Arizona’s coach was a pro coach and you could clearly see him saying run it run it again. He’s looking at BYU’s alignment and realizing that they are outmanned in the box. Tuiaki can’t see it.
Another interesting thing they do is on second and short they basically concede the first down to the other team. Byu often uses three lineman and positions the linebackers way back so that they cannot possibly stop the gain. I think part of this is because they believe that it’s better to give up the first down and start with a new set of downs or they think the other team may try to pass on second and short? The red zone defense inside the 10 yard line also often does not place enough defenders at the line of scrimmage and is susceptible to rushing touchdowns.
