I don't know that lasting one entire season out of three, and it not even being his most recent season, is cause to consider a trade for him.
Garoppolo is Sam Bradford at this point in his career until he can prove he can stay healthy. He is also really lucky that Trent Dilfer got his team to a SB, otherwise his 2019 post season would always get brought up as the ultimate game manager stats.
I mean, I respect your opinion and know you have always loved him from way back when, but there is not much about Jimmy G that says give away draft picks for him. Sign as an FA? Maybe. But not draft picks.
I would probably give up a high 4th for Jimmy G, that could turn into a 3rd if Lynch wanted to wait until 2023 for the pick. BTW, I happen to agree with you on Jimmy G being injury prone and that's the main reason I think there's a solid case to be made for bringing TT back over Jimmy G. Lets see if Jimmy G can stay healthy this yr.
