1) Trade Jimmy asap. It won't happen though. They'll try and wait for the best offer and maybe dabble into the idea of playing him in 2022
2) Impending free agents:

DJ Jones, Tomlinson, and Jennings would be my priority. I don't love Laken, but its very hard for Kyle and John to find decent offensive linemen apparently. Tartt is going to be too expensive, so just let him walk. I also think this fanbase massively overrates K'waun. Not saying I wouldn't want him back if the price is right, but I'd personally be a little stingy with the price tag if he asks too much
Verrett, well, it was a tough injury. I just don't think we can take that risk again unless he wants to come back super cheap. I think we should just end the experiment. Same story with Mostert.
the rest, I couldn't care less what we do. Seems like replaceable talent, especially defensive line. I'm sure Kocerek can just coach up some other guys that can play at a high level. They should look for upgrades at premium prices for CB and OL instead of bargain bin shopping at the dollar store
At this point, I wouldn't be shocked if the team looks completely different next year
