Pete Carrol extended until 2025, so that would take him to age 74. But, for Pete, he has a 31 year old Wilson, so that's his QB for his contract.
BB, he doesn't know right now who is QB will be next season. If Stidham is worth a look, he'd have to get him into half the games at least in the second half of the season to see what he has. I think if BB doesn't like his QB options this off-season, I could see him calling it a career soon.
Right now, Jets/Jags appear to have the top 2 picks in the draft. Jets won't trade Darnold within the division. Would likely do something similar to NE and send him to the NFC if possible, like to SF, Chi, Min, Was, Dal before Indy, Den for example. And it depends who is in position to draft Lance. Don't see BB paying who Dak would want. Are Wilson, Jones, or any other QB going to step right in and get the Pats into the playoffs when they are in the same division as Buffalo/Miami now?
I think if it ends up that NYJ get Lawrence, and trade Darnold to SF for a first round pick, then SF cuts Jimmy G, I could see Jimmy returning to NE and BB would get what he wanted about 4 years ago.
