Success isn’t guaranteed in anything these teams do, it’s part of the game. Somebody has to win and somebody has to lose. If they go try to get a new QB via the draft, whose to say that he gives the same level of production that Dak has given? The odds are against it
it wasn’t just that Wentz and Goff were overpaid, they were legit bad last season. If the Eagles were confident they could get even the 2019 version of wentz he’d still be on the team. And hell the Rams still got to the playoffs and won a game despite Goff not being good. They sought an upgrade, got it and are now one of the favorites to come out of the NFC
The point is they weren't worth the money that they were being paid and neither is Dak. My complaint isn't sorely pertaining to Dak, but the concept in general of paying average to above average QBs $35-$40+ million dollars.
It's only 4 QBs I believe in the league are worth that kind of bread:
Brady
Rodgers
Wilson (even he's debatable)
Mahomes
