GatorNation links: Top impact freshmen

GatorNation has more from Florida preseason camp and recruiting.

Michael DiRocco writesInsider: This year's group of freshmen might not be as heralded as Florida's top-ranked 2010 signing class, but several players have the chance to make a significant impact. Here are the six most likely to contribute.

DiRocco writes: Florida coach Will Muschamp still doesn't know which quarterback will start the Gators' season opener against Bowling Green, but he does know that both Jeff Driskel and Jacoby Brissett will play.

DiRocco writes: Florida's quarterback rotation -- provided Driskel is healthy and cleared to play next week -- won't result in any changes in the offense.

Derek Tyson writesInsider: Four-star DeMarcus Walker announced his commitment to Alabama on Friday afternoon on ESPNU, but the nation's No. 3-ranked defensive end said later in the day that his recruitment is far from over.

Tyson writesInsider: With Walker announcing his commitment to Alabama on Friday, the Gators will now look at some options to replace the No. 24-ranked player in the country on their recruiting board.
