One of the most up-and-down recruitments of the past few weeks has ended with Marcus Roberson signing with the Florida Gators .

A 6'1", 180-pound cornerback out of Fort Lauderdale, Roberson is Maxpreps No. 10 CB and possesses excellent size and fluidity. After initially committed to Texas Tech (and defensive backs coach Otis Mounds, Roberson's uncle) before backing out and committing to Auburn earlier this week. But that commitment lasted less than 48 hours, leaving Roberson free to makes his final decision between the Gators and USC.

By pulling the trigger for Will Muschamp and Co., Roberson becomes just the third new commitment for the Gators since their new head coach's arrival and could help ease the sting if --as many expect -- other top prospects like Curtis Grant and Tim Jernigan sign elsewhere. It remains to be seen how successful a Signing Day this will be for Muschamp, but thanks to Roberson it's off to a top-notch start; according to Maxpreps' Stephen Spiewak, Roberson's decision has pushed the Gators to the cusp of the top 10 in the Maxpreps team recruiting rankings .
