GAINESVILLE, Fla. -- When Urban Meyer left Utah for the SEC, the Florida coach brought a faster style of football that left opposing defenses playing catch-up.
Meyer's explosive spread offense and swarming defense helped the Gators finish 13-1 and win the school's second national championship in football in only his second season in 2006.
But as the Gators prepare to defend their national title, Meyer is having to alter the way his team will play in 2007. With nine defensive starters gone from the team that blasted Ohio State 41-14 in the BCS National Championship Game, Meyer is having to show patience during preseason camp, which started Sunday.
"I think how you manage the game will be a little different," Meyer said Monday after the Gators ended their second preseason practice in stifling heat. "We'll have to slow it down or try to score. The good thing is we've got some playmakers."
Although the Gators still have plenty of weapons on offense, there are a lot of new faces on defense. Even with Florida's freshmen practicing at 5:50 a.m. Monday, the returning defensive players might have used name tags to become acquainted.
Gone are All-American free safety Reggie Nelson and end Jarvis Moss, a first-round draft choice by the Denver Broncos. All three linebackers are gone, and only one starter returns in the secondary with cornerbacks Ryan Smith and Reggie Lewis also having departed.
"The holes are very significant," Meyer said. "You just don't sit down and replace Reggie Nelson and Jarvis Moss and all the others."

Asked whether he was confident the Gators could build a strong defense before the Sept. 1 opener against Western Kentucky, Meyer said: "I'm not real confident yet."
The defensive line and secondary seem to be the areas of greatest concern. End Derrick Harvey, who led the Gators with 11 sacks last season, returns to anchor the unit. Redshirt freshman Jermaine Cunningham was working at end with the first-team defense Monday, and senior Clint McMillan and junior Javier Estopinan were the tackles.
Meyer said as many as six freshman defensive linemen could challenge for playing time before camp ends.
"It's like we're the teachers," Harvey said. "We've got to set the examples for the young guys. We've got talent, but it's young talent."
The secondary might be of even greater concern. Junior Markus Manson and sophomore Markihe Anderson are the leading contenders at cornerback, and senior Kyle Jackson is the top candidate to replace Nelson. Senior Tony Joiner returns after starting all 14 games at strong safety in 2006.
In the first two days of practice, Florida's cornerbacks struggled to cover returning receivers Andre Caldwell, Percy Harvin and Jarred Fayson. In Sunday night's practice, Harvin left Manson spinning so much on a pass route that the cornerback ended up on his rear.
"Going against guys like that, it's going to make us better," Manson said. "A great cornerback will get burned sometimes. It's about how you do on the next play."
Freshmen also could make an impact in the secondary. Joe Haden could work his way into the cornerback rotation, and Moses Jenkins and Major Wright are candidates to play safety. Meyer said Lorenzo Edwards, who was recruited as a safety, is big enough to play linebacker.
The Gators have another eight days to evaluate their personnel on defense before the first preseason scrimmage on Aug. 14. After that, Florida will begin installing its game plan for Western Kentucky.
"We have to accelerate the learning curve," Meyer said. "We can't waste time."
