EJ Manuel knew that Florida State's offense had a tough job to do, keeping pace with Clemson's face-paced and potent attack. Slowed by a costly fumble and two missed field goals in the first half, the fourth-ranked Seminoles used a 35-3 run in a 20-minute span of the second half Saturday night to remain unbeaten with a 49-37 over 10th-ranked Clemson.
