Starting at quarterback as a true freshman requires two things, both exceptionally rare, more than anything else: prodigious talent and a golden opportunity.
Jameis Winston, for example, had the first without the second two seasons ago, despite being the top-ranked player at his position.
He sat behind future first-round draft pick EJ Manuel and took a redshirt during his true freshman year. Then, to prove his bona fides at the position, he won the Heisman Trophy and led Florida State to the national title the following season.
A player must have both to start right away.
Doing so is not unheard of, though, as proven by blue-chippers like Christian Hackenberg in 2013. He and Davis Webb at Texas Tech both bested the odds and got significant playing time for a power-conference team right out of high school.
With so much time between now and next season (sigh), it's hard to know for sure which guys stand the best chance of following suit.
But in terms of both talent and opportunity, some stand far ahead of their peers.
