Athens, Ga. ? Georgia’s offense finally showed up, and the Bulldogs now truly look like a team capable of challenging for a national championship.

And LSU? The Tigers’ hopes of making another run at No. 1 are finished.

David Greene set a school record by throwing five touchdown passes, and No. 3 Georgia got a huge victory in the Southeastern Conference, shredding 13th-ranked LSU and its fearsome defense, 45-16, Saturday.

“It was something you probably just dream about,” Greene said.

Georgia (4-0, 2-0 SEC) never has been an offensive juggernaut during Mark Richt’s four years as coach, and the last two games were frustrating. The Bulldogs scored three touchdowns in defensive-led victories over South Carolina and Marshall.

“I was little befuddled,” Richt admitted. “We had practiced extremely well. We had some guys who could make plays. I was trying to figure out why we couldn’t make those plays in the game.”

Problem solved. Less than 21 minutes into this one, Georgia already had reached the end zone three times against a defense that was ranked fifth nationally in both points and yards allowed.

By the end, LSU (3-2, 1-2) had given up its most points since a 56-13 loss to Florida in 1996.

“This was a curveball to me,” Tigers coach Nick Saban said. “When things like this happen, you must dig deep down inside.”

Georgia's Reggie Brown makes a leaping catch for a touchdown as LSU's Travis Daniels trails. The third-ranked Bulldogs pounded the No. 13 Tigers, 45-16, Saturday in Athens, Ga.

Greene completed only 10 of 19 passes for 172 yards, but half his completions went for TDs. He tied Johnny Rauch as the winningest quarterback in Georgia history with his 36th victory as a starter.

Reggie Brown had two TD catches and set a career high with 110 yards receiving. Fred Gibson also had a pair of scoring passes.

The Bulldogs didn’t just pass the ball. Freshman Danny Ware, who sat out the last game with a bruised lung, rushed for 109 yards. Another freshman, Thomas Brown, chipped in with 81 yards and scored Georgia’s final touchdown on a short run.
