Those have way more to go with the kicker than you want yo admit. The one against Wisconsin was a direct result of not kicking it in the end zone. And, if you don’t do that, get enough hang time for coverage to get down field. I don’t remember the one against Iowa specifically. But, I’m going to guess it’s the same.
I have no clue how good this guy is with special teams. But, I’m pretty sure they will be better next year than last season.
