2013 Top 25 player countdown: No. 7

No. 7 Bryn Renner, QB, North Carolina

Previous ranking: No. 20

Making the case for Renner: He’s one of the most underrated quarterbacks in the country, but his value could be proven come draft day. Renner enters his senior season on the brink of setting nearly every career passing mark at UNC. The three-year starter has thrown for more than 3,000 yards in each of the past two seasons -- the only player in school history to hit that milestone twice in his career. He set the single-season school record for total offense last year with 3,394 yards. Renner has flourished in coach Larry Fedora’s spread offense, and should be even better this fall because it is the second season with the staff and he’s more familiar with the playbook and expectations.

Renner currently holds the school record for career 300-yard passing games with eight, but even more impressive has been his efficiency. Last year he started all 12 games, completed 65.4 percent of his passes, and threw for 3,356 yards, 28 touchdowns and just seven interceptions. Renner enters the season with a career pass efficiency mark of 154.6, which ranks fifth among all FBS quarterbacks. If he keeps up that pace, he would break the current ACC career pass efficiency record of 151.2 set by Florida State’s Chris Weinke. Not bad company.
