I'm all for it IF he hires a strong offensive staff.
Bring in a bunch of old dudes and right this ship.
I would not be excited at all about a Marvin Lewis hire. However, in some ways, it's like eating vegetables. You might not like it, but you might need it.
The Bengals are the worst franchise in the NFL, bar none, and he made them a perennial playoff team. Obviously he didn't have success in the playoffs, but if he did, he would still be in Cincinnati.
And like you said, if we do hire Marvin, we need a strong offensive staff.
