n/s Could the Raiders start a coaching trend ?

Cowher, possibly

Coughlin is like 85 years old

Shanahan is also getting up there

Brian Billick was an offensive specialist whose Ravens' teams won on the backs of a defense. Kind of like Gruden I suppose. But Gruden did do some good work with Rich Gannon on the Raiders before he became Tampa's head coach. I think Gruden has a ceiling though unless his team also has a great defense and an FO gives him a good QB. He wasn't good at picking the QBs on his own.

Steve Marriucci , Jim Fassel and Jeff Fischer didn't win Superbowls, though Fassel and Fisher did get to one. Their teams also didn't sustain success. So not exactly comparable
