The Washington Huskies made it to the College Football Playoff two years ago, and they could get back there this season if Aaron Fuller emerges as an X-factor in the receiving game.
Alabama, Clemson, Ohio State and Georgia have been well-established as the preseason favorites to reach the CFP. Those teams don't need X-factors to become the best in the country. They just need to avoid injury and live up to that potential better than Florida State and USC did last year.
However, there are more than a dozen teams just on the other side of that cut line who could vie for a national championship if just one breakout candidate lives up to his potential.
