I don't think it's that with Olave...maybe he sees Carr the way some of us see Carr as an usurper QB undeserving of chewing him (Olave) out when his own sheet (Carr) isn't up to par.
Which comes back to coaching...no one is holding Carr or anyone accountable leaving it up to some guys trying to do it themselves, but those same guys are messing up themselves and their stuff is going unchecked
