I agree that it's almost impossible to be certain about player performance without knowing the play call and individual player responsibilities within that call/scheme. There will always be a certain amount of conjecture in that regard. It's possible that Savea, Lole, et al. did exactly what they were tasked to do within the scheme. If I have time (ha ha, things are busy right now), I'd like to go back and focus on the interior D-line and see how they fared in terms of stacking up blockers and avoiding getting turned or pushed off the LOS.
I also agree with you that our running game efficiency wasn't that good against CSU. Lots of stuff to clean up. The interior O-line getting beat on several occasions is somewhat worrisome given that both Grant and Graham of UM's defensive line will be playing on Sundays in the future. That's a critical matchup.
