I don't know if the Raiders will be as good as you hope. That division is STACKED. Lots of losses - Chiefs, Chargers, Broncos - that could be 1-5 or 0-6 just to start! Sure they play four 4th place teams and two 3rd place teams, but ... tough sledding.

But, the Raiders have a history of very young offensive coaches being special.

Gruden, as you mentioned, and who they should have kept.
Shanahan, whom they got rid of way too soon.
Madden, likely the best of the bunch.

This "kid" has been around football his whole life. His dad was the architect of the Tampa Bay D. If that team had any offence, they would have had more than 1 championship.
