Don't forget, the Walton family owns the Donkeys now. They have more than enough money to fire the entire coaching and admin staff, buy them out, and start over. Which I somewhat expect them to do. They didn't hire this current staff. Only the team president, who was hired after all the off-season trades, is likely to remain.
I agree that while Wilson will likely never be the player he was in 2017, it's inconceivable he plays this bad under a new system next year. Yes, he's dropped off. Yes, steal of the century for Seattle. But there's something grossly wrong, likely many things wrong, and there is no way they are just going to release him. Worst cap hit and dead money in NFL history if they did that.
Lance still does remain somewhat of an unknown. Ideally he will be the next Jalen Hurts for SF, right? But....who knows? I guess we'll find out next season. As I said before, even if Jimmy G wins the SB, he's gone. You don't give up what SF did to move up in the draft to get Lance to not give the offense to him at some point.
As to Watson, I believe with what they coughed up in both picks, and money, and what he and his agent promised in convincing Cleveland to pay him that much, not only would I expect him to win at least 4 of their last 6 games (tough games are Balt and Cincy), and look increasingly good, like a true impact player when the season is over. I also expect him to take the team to the playoffs, probably the division title, and beyond next year. Remember, he wasn't paid money to make them improve, he is paid Super Bowl MVP level money. The Browns have an excellent OL, good receivers, one of the best RBs and maybe the best RB tandem in the league (Hunt will be gone next year though). Their defense is good overall with some depth. They now have a fairly solid coaching staff that is on the same page, and an offensive and QB friendly coach. There's no rebuild from here on. It's, here's a lot of money Deshaun, now get it done, get us to the Super Bowl in a couple years, and win it, period.
