Gabbert was a straight bust. Probably should have gone back to school. He also had like 10 different offensive coordinators. Locker was a weird pick, a ridiculous athlete who had some ups and downs and retired early. Ponder was way over drafted. People had him going in teh second or third round. He is a slightly smaller Mason Rudolph and is why you don't draft quarterbacks with limited athleticism and noodle arms in the first round.
To me Rosen is the most bust proof of the guys this year, and maybe Darnold. Rosen's red flag is teh concussions. Allen has huge upside. Outside of those three, I don't really understand the love for guys liek Mayfield and Rudolph. Very limited athletic ability. Jackson is boom or bust.
