A quick overview of each position in the ESPNU 150:
It's a slightly above-average year for quarterbacks. We have two prospects in the top 20 of the ESPNU 150 with FSU commit Jameis Winston (Hueytown, Ala./Hueytown) and Indiana commit Gunner Kiel (Columbus, Ind./East) -- but Winston is a top baseball prospect and might not even play football. It's a class in which a lot of players bring something different to the table and also features some talented but slightly under-the-radar signal-callers who would surprise at the next level like BYU verbal Tanner Mangum (Eagle, Idaho/Eagle). It can be tough for quarterbacks to make an immediate impact, and while there are plenty of talented QB prospects -- we have 20 guys graded at 80 or higher -- most will need time to develop and adjust to the college level. Two who could make an instant impact are Kiel, who has the tools and the situation at Indiana to be able to play right away, and Zach Kline (Danville, Calif./San Ramon Valley), who is one of the more polished QBs in the class and fits the mold of past successful Cal QBs.
