So even if this happens, what are we talking about. He manages to be back for maybe the final 4 games? If the Jets are still hanging around (big if), chances are there's some rust to work off. Dec 17 @Miami, likely loss, 24th vs. Wash, pencil in a win but no sure thing, 31st, @ Browns, loss although there's a chance, Jan 7 @ NE, maybe their first win vs. the Pats in forever. That's 2-2 likely with Rodgers so it means Wilson will have to win the next 4 games to give them 11 wins or go 3-1 for 10 wins and a maybe play-off spot. And all this is contingent on Rodgers not getting hurt again.
If you are on the last legs of your career and not worried about re-injury or long term effects I guess it is possible
