while I think GB would play well, I don't think he would take the physical risks that Jake would to get a win, ala the
run before the pass for Lassiter's TD. I think he'd love to get in, get snaps, and probably play well, but I also have to think he'd do pretty much anything to prevent risk of injury knowing he's headed for the draft.
Jake plays with a little 'reckless abandon', he can afford to because he has a backup, and he knows he can come back next season.
