Louisville QB Lamar Jackson will apply for early eligibility to enter the 2018 NFL Draft, signaling the end of a three-year career in which the Cardinals star became the most exciting player in college football. He announced his decision on Friday via Twitter. Jackson won the 2016 Heisman Trophy as the nation's top player, and was a finalist for the honor in 2017. He flourished as a dual-threat quarterback under coach Bobby Petrino with a rocket-strong arm and electrifying rushing skills, drawing comparisons to former Atlanta Falcons first-round pick Michael Vick. NFL.com analyst Bucky Brooks sees footwork and mechanics as areas in which Jackson needs to improve as a passer, specifically to improve his accuracy. Jackson is considered one of the top quarterback prospects in the college game, along with UCLA's Josh Rosen, USC's Sam Darnold, Oklahoma's Baker Mayfield and Wyoming's Josh Allen.
