Griffin and Cousins should have a legitimate competition this offseason. They need to be on equal ground in the teams' eyes before training camp starts. Give the job to whichever performs better in the next 8 months.
Meanwhile, we need to continue to improve the offensive line. Not by signing high-dollar free agents and not necessarily by using high draft picks, but keep signing these young free agents like Nixon and Larsen, and draft some more offensive linemen late and maybe a developmental center in the mid rounds. Try to get better at tight end and running back when it comes to pass blocking, whether that's through value free agents or the draft.
After the season's over, evaluate your starting QB... if he played well enough to stay, commit to him with an extension and move on from the loser. The moves we made this year as well as the OL picks we took last year should start paying off to a larger degree and this should help the starter continue to improve.
If your starting QB played poorly, well, you're in the market for a new guy with both Griffin and Cousins walking.
I also think we should let McCoy walk and either draft or sign a rookie QB to start developing.
