Darnold still sucks and Bridgewater went on to leave here and accomplish nothing.
Mayfield was never bad, that was just being stupid.
You can hope and wish all day long but Bryce doesn't have a tenth of the talent or abilities of a single one of those QB's you mentioned. That's the difference. It isn't like he has all this upside to make people believe. He has almost none.
Good luck with your journey to finally realizing what most of the rest of the NFL world has already figured out.
