Tyler Murphy, Florida, QB: Forced into action three weeks ago against Tennessee after Jeff Driskel went down with a season-ending injury, the QB once ranked as a "two-star" recruit and the nation's 148th best wide receiver prospect in the country has been a godsend to the Gators. Murphy's completing over 75 percent of his passes and has a 5-1 TD-INT ratio. The 6-2, 210-pounder's also run for two more TDs and has had a carry of at least 15 yards in each of the three games he's played. Another telling stat: Murphy's averaging a robust 9.82 yards per attempt. That's more than three yards per attempt more than Driskel did in 2012. 9. John O'Korn, Houston, QB: Tony Levine had a rough debut season last year with the Cougars, and things didn't get any easier when he lost star RB Charles Sims, who would've been the American's top running back, on the eve of this season. Sims bailed on UH, and veteran QB David PIland had to retire due to concussions, but true freshman O'Korn, a 6-4, 205-pounder from Fort Lauderdale, has been a revelation, throwing 10 TDs against just one INT while also displaying some decent wheels in piloting a talented but young crew of receivers. Houston's also gone from No. 82 in turnover margin to No. 1.
