USA TODAY Sports' freshman All-America team

They are only freshmen. But across the country, first-year contributors have grasped major roles for some of the nation’s best teams – including at undefeated and No. 1 Alabama, which starts true freshmen at quarterback and offensive tackle.

The Crimson Tide’s Jalen Hurts and Jonah Williams have starring roles on the USA TODAY Sports Freshman All-America team, which includes at least one representative from each of the 10 conferences in the Football Bowl Subdivision.

Also honored are Ohio State running back Mike Weber, Penn State offensive lineman Ryan Bates, Clemson defensive tackle Dexter Lawrence and Washington safety Taylor Rapp.

The nation’s most accomplished freshman, Houston defensive tackle Ed Oliver, earned a rare double-feat: Oliver was a Freshman All-America pick and a first-team USA TODAY Sports All-America honoree.
