Breaking down the tiers of quarterback prospects…
Andrew Luck: Stanford (6-4, 235)
Doesn't have an elite arm, but is a "plus" in just about every other facet of the game. Is about as safe a franchise quarterback prospect you can find.
ICONRG3 looks like a lock for the second pick in the draft.
Robert Griffin III: Baylor (6-2, 220)
A "plus" athlete who can really throw the football, is a student of the game and is only starting to scratch the surface of his potential. Has as much upside as any prospect in the draft and looks like a future franchise signal caller.
Ryan Tannehill: Texas A&M (6-4, 222)
With such limited experience at the quarterback position it's not a case of where this guy is right now, but where he can be in 2/3 years. I love the talent and the overall production from a guy who doesn't have much experience playing from under center as he plays way beyond his years. A potential franchise quarterback in my mind.
Brandon Weeden: Oklahoma State (6-4, 218)
His age will likely keep him from going as early in the draft as his talents deserve. But there isn't a throw this guy can't make and he has the skill set and mental make-up to mature into a potential starter with some time.
Nick Foles: Arizona (6-5, 240)
A big, strong-armed passer who has the tools physically. Made some real strides as a quarterback as a senior without much talent around him. Is going to take some time, but is an potential starting caliber pocket passer.
Kirk Cousins: Michigan State (6-3, 205)
A solid athlete who isn't overly impressive physically, but he has enough to make it in the NFL. Needs to take that next step in his understanding of the offense this year and cut down on the mental errors. However, he's a good kid, a hard worker and has some real similar qualities to some of the senior quarterbacks who came off the board this year (Ponder/Dalton). Nevertheless, his struggles with pressure could hold him back from ever becoming an NFL starter.
