As we count down 50 days until the start of the 2014 college football season, ESPN Insider Travis Haney is answering at least one big question a day until South Carolina and Texas A&M’s kickoff on Aug. 28.

Heisman contenders, breakout freshmen, conference winners -- it will all be covered as part of Insider’s Ultimate Season Preview.

Today’s question: Who will be the Heisman front-runners entering 2015?

I’ll make a selection from these three categories: (1) returning players with experience, (2) players on campus with no experience (2014 freshmen) and (3) Class of 2015 recruits.

Returning players with experience: Penn State QB Christian Hackenberg

Hackenberg certainly had his moments as a freshman, but he was still 75th in QBR (58.9 completion percentage, 20-10 TDs-to-INTs). There’s room to grow, and first-year coach James Franklin is decidedly enthused to inherit a high-end prospect he once recruited.

“As good as I thought he would be, he’s better,” Franklin told me recently.
