The Dolphins would have to be insane to not take a QB if there's a guy they think would be worth the Texans' pick. Look at Tua vs. Fitz tonight, it's certainly not because Fitz is playing with better receivers.
Out of the 3 crappy QB options on that team, I think Newton is still the best. Stidham and Hoyer are stiffs and aren't any better at avoiding turnovers than Newton.
I mean, maybe he's a bad pick, but I think people overvalue 3rd round and later picks... substantially. It's more the intensity of the reaction that leaves me puzzled.
