When Driskell is ragging on a coach, 99% of the time it's because that guy gives other reporters quotes/access but doesn't give any to him. There is a lot of bad blood between certain coaches and Driskell. Driskell also hates being wrong, so when he gets exposed on certain takes (OL play, Long, Rees, Jurkovec, Allen, etc.) he simply waits until that passes and some other data point comes along that he can cherry pick to prove himself "right."
With that being said, the OL is probably going to struggle a bit this year. Not because of bad coaching, but because of mediocre recruiting for a couple years that left the cupboard bare of developed upper classmen. Cain Madden was a GREAT addition and makes me more optimistic that -- barring injury -- the OL will have its crap together.
