Based on what I've seen, Jared Goff is the jewel of the 2016 QB Class followed by Cardale Jones. Cardale has massive upside but Goff is that prototypical pocket passer. He reminds me a lot of Sam Bradford after Sam's first year at Oklahoma...skinny kid but insane arm talent and very composed in the pocket.
I also really want to see Carson Wentz. 6'6" 230 with mobility and a strong arm. One of the top FCS players and NFL scouts are apparently very high on him...no surprise. I gotta see where his pocket presence, mechanics, and accuracy are at.
I'm not a fan of Cook. Not poised enough in the pocket or consistent enough with his accuracy for me. Hackenberg has all the physical tools but he needs to progress and show consistency in 2015. Although, Franklin's system and his supporting cast did him no favors.
Kiel is a good talent but he doesn't have the physical talent of the other top guys and needs to stay healthy. But I want to see how he progresses this year. Physical talent is overrated and he showed a lot of positive traits last year which was his first as a starter.
Brissett has a long ways to go for me. Very Brett Hundley like...project QB at this point.
A couple other names worth mentioning:
Trevone Boykin QB TCU - Very RGIII like imo with his skill-set but that's not a bad thing (good arm and great mobility but he still chooses to hang in the pocket). I'd need to know where his intelligence and character are at to feel comfortable with him but definitely an intriguing prospect. Hate that he's coming from an Air Raid offense, though.
Cody Kessler QB USC - His instincts and mechanics are sound but I see him as more of an overachiever and a college QB. Think he'll make a great backup but not sure he has the talent to be a long time NFL starter. A lot of things in common with Garrett Grayson but Grayson was more physically talented and had better poise under pressure imo.
Jeremy Johnson QB Auburn - Will be his first year as a full time starter but he's got Cardale Jones like talent and did play in 2014 and 2013. He's showed great things thus far when he's played. 6'5" 240 with mobility and a very strong arm. We'll see how he does as the full time starter but flashed the potential to be a top 10 pick in 2014 when he played. If he lives up to his potential and continues to play well, he could push Cardale and Goff to be the top QB selected.
A couple smaller school guys worth keeping an eye on are Paxton Lynch from Memphis and Brandon Doughty from Western Kentucky. Haven't seen much of either yet, though. Zach Terrell from Western Michigan is another.
Brad Kaaya from Miami is also a name to watch but he's not eligible next year. He'll be a top prospect in 2017, though. J.T. Barrett will also likely be a top prospect in 2017 assuming that Cardale starts in 2015. Same with Deshaun Watson from Clemson in 2017.
Another guy that I felt showed some flashes of good things is Patrick Towles from Kentucky but I doubt he enters the draft early in 2016.
There are also some people very high on Nate Sudfeld from Indiana and Wes Lunt from Illinois also has fans because both are big, prototypical pocket passing types.
Justin Holman and Will Gardner are both big guys with guns but they need to show more consistency.
Everett Golson is a small guy with an arm but he, too, needs to show more consistency.
Dak Prescott and Kevin Hogan haven't been mentioned yet because I'm not high on either.
