In his 3 seasons, he's posted passer ratings of 77, 84, and 65. His career passer rating is 78.
To put that in perspective, Dak's career passer rating is 97 and our trash heap of a fanbase thinks he's terrible. Dalton's career passer rating is 87, and he was a bottom-shelf, bad starter. A guy like Darnold, with his passer rating 10 points worse than Dalton's, is a mediocre backup, basically. And he's got 1.5 seasons left on his contract.
Exercising his 5th year option means paying him the average of the top 10 QB salaries, if I understand right. We'd be insane to do that. So we're talking about spending a 3rd rounder on a 1-year rental of a mediocre backup.
No thanks. Not even a littler interested in this idea.
