It's all about team building. Russ IMO is not a cornerstone player, he's the opposite of that.
Russ is an aging player who won't be around long term, has lost foot speed, and has an injury history that can't be ignored. Then, add in issues with chemistry and commitment, for me it's 'just say no'.
IMO we should draft a rookie QB and some OL to protect that QB, and build out from there. If we miss on the QB, then we'll suck again and be in position to draft another QB high next year.
We go nowhere till we have a long term answer at QB, IMO.
Having a rookie QB on cheap money for 4-5 seasons is the best advantage one can have in the modern NFL, IMO.
