Does anyone have a sense of the “work” Derek Carr puts in?

Nobody, not a single soul, thought our o line was going to be a weakness this season
About that....

Is it really though?

QB is only a big enough need to those that don't understand how much coaching/scheming/playcalling affects that. With better coaching, we could have won 10 plus games this season. Crap, we won 9 last season with 4 different quarterbacks. On the offensive side, QB was the least of our issues. The offensive line and running backs being liabilities were our biggest issues.

I saw the O-line as the biggest issue we had last season (outside of coaching) and we made no real changes there.
