All three will have two years of starting experience after this season, so although they are only redshirt sophomores, they'll have the same amount of playing time as some senior prospects like LSU's Zach Mettenberger, who is in his second year as the Tigers' starting quarterback.
Q: You're the GM of an NFL team with a top 10 pick next spring and need a franchise quarterback. Teddy Bridgewater and Tajh Boyd are off the board, are you going with Hundley or Mariota?
Rang: At this early juncture, I'd lean toward Hundley because I have seen him respond well in pressure-packed situations. Mariota is an exceptional athlete with a first-round arm but with the Ducks so frequently in control of games by halftime, I need more evidence of his poise. Needless to say, to warrant my consideration this high, the quarterbacks would also have to demonstrate the football intelligence and leadership in pre-draft interviews.
Brugler: I'm leaning Mariota at this point, but its close. Mariota is more decisive than Hundley at this point in their careers and I trust him a little more. Both will be fun to watch, especially when they go head-to-head Oct. 26 in Eugene.
Q: Because no football conversation is complete without mention of Johnny Football, why are Hundley and Mariota better NFL bets right now than Manziel - who isn't in either of your first-round mock drafts?
Rang: For me, it's simple. To this point, Hundley and Mariota appear to have the leadership traits I value at the quarterback position. There is no question in my mind that some scouts will give Manziel a first-round grade, as he is an extraordinary talent in much the same mold as former Pro Bowl quarterback Jeff Garcia. Manziel will not actually be drafted this high, however, unless his actions on and off the field earn the trust of at least one NFL franchise.
Brugler: More arm talent and reliable as passers. Manziel is a fascinating NFL prospect, even more so than Tim Tebow was, because he has the talent to make plays in the NFL. The big question with Manziel is, how reliable can he be? He gets away with a lot of throws and decisions that won't work at the next level. Can he adjust and adapt in the pros? That's the big question.
To be perfectly honest, I think Manziel ends up in the first round next May, but I also think most teams will have Mariota and Hundley higher on their draft boards.
