For me it's both of those quarterbacks. Trey Lance and Fabio.
However, I still believe Trevor deserves to be the first quarterback off the board. It's not a strong quarterback class. I think Trevor has plenty of tools and will likely make an average pro, but he's overrated based on the hype. He's been everything from the best QB prospect ever to the best since Peyton Manning to the best since Andrew Luck.
The reality is he's been overhyped ever since he made his name off one game against a bad Alabama defense where he faced no pressure and the receivers running wide open because the DB's were laying on the ground. A game where Tua was throwing pick sixes and Mike Locksley had no clue what he was doing. Since then Trevor has done absolutely nothing other than pad stats against bad competition and look like a complete goober against good competition. Followed by starting off his sophomore year by throwing 5 picks in his first 3 games.
In essence, right now he's a one read QB that looks great throwing up 50/50 balls on plays that he's already determined where he's going before the snap.
Better quarterbacks have faced far more scrutiny than he has. And I'm not sure why.
