Rodgers has all of the leverage here. Not traded? Fine, he retires. He'll be hired immediately as a talking head, might end up the full time Jeopardy host, and is all set financially unless he's been a complete spendthrift. Plus he doesn't have to worry about that one hit that'll do permanent damage.
Plus his historical legacy is pretty secure. He's already got his SB and even if he could go on another run he'll never eclipse Brady. Sure, he can climb the leaderboard for the various counting stats but so what, he's never going to be unambiguously better than Brees, Manning, etc.
