Sounds like there's even some minority owners who want Tomlin out of there.
IMHO, the Steelers are on a downward trend regardless of who is coaching. Ben is getting long in the tooth, Bell seems to be focused on money first, and while I can't fault him for that, he could easily be on his way out. The defense has some talent, but also some big holes.
I'm not saying they're going to go 3-13 or anything like that, just closer to .500 than they usually are. If they keep the core together, they've got 1 or maybe 2 seasons left in their window.
