Last Team to Tank a Season and Win a Super Bowl a year or two after?

It's not so much about tanking as it is finding a way to find the QB. Tanking is the most obvious way to get there. I mean, you could luck out and Rattler is the next Warner or maybe Purdy (who I'm not sure how good he is), but however you do it, you need to find the next Burrow, Mahomes, Daniels, etc.
