My sense tells me it's a symptom of youth and inexperience. We've got a bunch of players who are playing a lot of snaps a year earlier than they would otherwise. In the trenches that makes a big difference. Not much can replace time in the weightroom and at the training table, and reps learning how to play a position. Which is why our handling of guys like Irving and Morrissey are such a kluge. No redshirts for either of them - what a fustercluck. Morrissey was a 19-year old junior for crying out loud. Same with Irving I think, at the start of the year. Coe doesn't get a redshirt to learn what he's doing because we've not nobody.
Injuries, like on the OL, happen and no one can predict it. Mostly it looks like a team relying too heavily on young/inexperienced guys in the trenches.
