Countdown to college football: 4 days

Glenn Beil/USA TODAY Sports

With a redshirt freshman quarterback in Deondre Francois starting Florida State's opener against Ole Miss on Sept. 5 (8:00 p.m. ET, ABC), running back Dalvin Cook will be counted on to pace the Seminoles' offense.

Last season, Cook rushed for a school-record 1,691 yards, breaking a 20-year mark set by Warrick Dunn in 1995. For Florida State to get where it wants to go, Cook might have to duplicate his impressive 2015.

FSU enters 2016 as the No. 4 team in the nation in both polls, and ESPN's Football Power Index gives the Seminoles a conference-high 45 percent chance to win the ACC.
