This is the basic truth of the matter. Their QB play for them is sup par. The defense misses NarDuzzi. That wouldn't show up the first year it will show up in the second and beyond. It may happen to Wisconsin in the next few years without Aranda. I think they got a little compacent and have lost their edge.Well...they went from having back to back NFL QB's...to not having that and instead have a statue QB that also can't throw.
They have lost their DC who is doing a good job at Pitt and after while that was going to catch up to them.
They also loved living off the "no on respects us" bit...that only works for so long.
