There's a difference between overpaid and overrated. Lawrence and Watson are massively overpaid but from what I can see are widely viewed as being below average/garbage QBs that didn't deserve their contracts.
To me, a guy that I think a lot of people view as elite because he's been to the Superbowl and scores well in fantasy football is Jalen Hurts. However imo he's just not a good passer and only scores as many rushing TDs as he does because of the tush push and not because he's in the Lamar Jackson/Jayden Daniels tier of running QBs. I'd put Purdy right behind him as second most overrated but there's some bias involved.
