The season is over, they would have to win 6 out of 7 to only have a slim chance at the playoffs based on wins by SF and MIN.
So with that, this is what needs to happen the rest of the season or before next season. Fire Pace, fire Nagy and the entire coaching staff. You have to get the stench off this team and the only way is to clean house. Allow the new GM to come in and hire his guy. On offense, draft/sign a Center and WR, don't sign ARob, don't resign Monty. On defense, shoot Vildor to the moon, draft/sign a starting CB, Safety and ILB. Don't re-sign Nichols, only bring Hicks back on a one-year deal.
To end this season, I would bring up Adams to see what he can do. You might as well cut Byrd. I would sit or put as many vets on IR as possible and get an extended look at some of the younger guys.
