I realize from the PSU game on that were not rotating defensive lineman as we were told and hoped this year by how much I seen Bosa but until I read what Adolphus Washington said after the MSU game was I really concerned about it. He clamed that he was so tired in the fourth quarter that on a screen pass he was chasing down that when the back changed direction all he could do was fall on his butt. My question to all of you is at what point do you risk a substitution from an average backup to keep your starters fresh. If we make it to the playoff things like this could mean winning and losing. The season is starting to get long now and the possibility of wearing these four down would not be good. Thoughts?
