It's no real suprise.
Shell was the absolute last option for grampa Al.
The Raiders took their time looking at potential coaching candidates, and those they did eyeball wanted nothing to do with that organization.
They were left with the only person who was insane enough to consider the job.

Shell was never meant to be more than a 1 and done coach.
I think in some way even he had to realize that.

Oh well, I can't complain and I don't feel anything but utter joy at the Raiders failures.

"F" the Raiders. ;D ;D ;D
