Most important thing for Gruden is having Carr at QB, who is a 4 year starter already. That's the key for him to have a QB to work with.
Will Gruden last the whole 10 years? No, I doubt it. But, if I were making $7 mill at ESPN to work pre-season in August to early Jan for the 1 playoff game and do the Pro Bowl, it would take a lot to get me to give that up. And I have Feb - Jul to do public speaking engagements for 5 figures a pop and hold my QB camps and stuff, I'd want a significant amount to take on the added stress and time.
Challenge for Chucky going forward:
1) Add depth to their expensive OL.
2) Find a new RB. I would think this was Lynch's only season in Oakland.
3) Upgrade the secondary. Need Joseph, Conley, and Obi (Safety) to do something.
4) Need upgrade on DL to put pressure on the QB.
They hold pick #9/10 in the draft, so plenty of options to get help on the DL or secondary in the first 2 rounds. Grab a RB in round 3.
