Florida quarterback Tim Tebow said he emerged from the spring "100 percent more comfortable in the pocket" than he was last season. Tebow told me he has a quicker, refined delivery and is more accurate underneath. After leading his team to a 27-0 advantage at halftime of the Gators' spring game, Tebow said he's identified Florida's inexperience on defense "could create some problems," but adds that despite the loss of nine starters, the unit is faster overall. Earlier in the spring, Tebow told me he spent part of last year's national championship week eating In-N-Out Burgers with former Utah quarterback Alex Smith and discussing the style of offense he'll run this season for Urban Meyer. Tebow also said that at the Elite 11 quarterback camp, he threw a pass 75 yards, backing up the notion he has a stronger arm that Chris Leak. Arkansas running back Darren McFadden told me he doesn't have time to worry about how to win the Heisman Trophy, he's been trying to figure out all the blocking schemes of new offensive coordinator David Lee. McFadden said he's never seen a playbook as thick at Lee's. Returning quarterback Casey Dick should be pleased to know that Lee returns to Arkansas from the Cowboys, where he worked closely with quarterback Tony Romo. The quarterback thought so much of Lee he invited the coach and his wife to Hawaii for the Pro Bowl. Georgia quarterback Matthew Stafford had his growing pains as a true freshman. But after this year's "G" game, coach Mark Richt told me Stafford has "gotten all the dumb plays out of his system." Richt started Stafford as a true freshman because he said he's the best passer he's ever coached, including Heisman winner Chris Weinke. One of the adjustments Stafford's made? Not trying to throw fastballs on every play. Georgia's breakout star of the spring? Running back Knowshon Moreno. "Now that's a playmaker," Richt said. Tennessee offensive coordinator David Cutcliffe told me his plan to install a no-huddle offense was stalled by a mid-spring injury to starting quarterback Erik Ainge. But he also notes that the Vols will rely on some inexperienced receivers who weren't available in the spring anyway.
