College football returns plenty of stars at the quarterback position for 2019, but there's another wave of players ready to emerge with a breakout year. Alabama's Tua Tagovailoa, Clemson's Trevor Lawrence, Georgia's Jake Fromm, Texas' Sam Ehlinger and Oregon's Justin Herbert are just a few of the big names returning this fall, while Nebraska's Adrian Martinez and Ohio State's Justin Fields could join the list of top 10 quarterbacks with a big year. Both Martinez and Fields make Athlon's list of top breakout quarterbacks for 2019, with Florida State's James Blackman, Ole Miss' Matt Corral, Texas Tech's Alan Bowman, Iowa State's Brock Purdy and Syracuse's Tommy DeVito headlining the next tier.
