I think we should. The buzz out of Spring Ball is that the defense is dominating the offense. That Michigan's defensive line and LB core are stifling the offense line and pressuring any QB that Michigan puts up there.
In the end, I think Michigan's offense line will be fine, not too many opponents will have 2 NFL 1st rounders on it. Michigan is solid at TE and RB. The issue is with the passing game, Orji is more of a runner then passer. Davis I'm sure is talented but still young and inexperienced, Warren looked really good in a Spring Game a couple years ago and we haven't heard about him since, Denegal is reportedly struggling this Spring and 10 year man Tuttle is injured.
