Think it’s 90% offensive line and playcalling
I just can't agree on the play calling. Everyone loves to bag on play calling when more often than not, the execution wasn't there. That's not to say Sark hasn't made some shit play calls, but I think majority of the time it's failure of players to execute.
Arch isn't as far along in seeing the field and the game slowing down as we'd like. He has left a LOT of meat on the bone, but the trash OL is a large part of that too. A young QB will see ghosts on plays when the pressure isn't there, if it usually is. I wish Sark had allowed him more live snaps last season and to throw passes, not just use his legs. But he didn't want the controversy AND we often didn't have the kind of leads where we'd be comfortable enough to let him play. Shades of Mack Brown and Garret Gilbert.
