Gibson and Brown combined for eight catches, 166 yards and four touchdowns in Georgia's 45-16 romp of the Tigers.
"That's one of the things we've been waiting for, for both of them to step up and play well at the same time," receivers coach John Eason said.
Said Coach Mark Richt: "The game boiled down to our receivers against their DBs. If we don't make a couple great catches and a couple of great throws, they might have stoned us. They were either going to get us or we were going to get them."
Asked what the senior duo proved, Brown said, "that we're two of the best receivers in the nation. I don't want to gloat, but those were supposed to be the best corners around and we had a good day on them."
Added Gibson: "The game proves itself. It was on CBS. Everybody got a chance to see us against the cornerbacks one-on-one. They can be the judge."
In two games against the Tigers last season, LSU's cornerbacks dominated the matchup. Brown had nine catches for 133 yards. Gibson played in only one of those games and head three catches for 19 yards. Neither scored a touchdown.
Saturday was different from the start. Brown caught five catches for 110 yards and two touchdowns in the first half, none more impressive than a 29-yarder with 9:40 left in the second quarter. On first-and-10, quarterback David Greene threw a strike down the right sideline that Brown went airborne to catch.
"When I've got confidence in them, I might just hang it up there and let them go get it," Greene said. "Today was just a day when they were going to catch anything."
Brown was fourth in the SEC with 66 receiving yards per game coming into Saturday's game. He finished the game with five catches for 110 yards. Gibson had three catches for 56 yards. Freshman Sean Bailey got in on the act late, scoring his first collegiate touchdown with 1:59 left in the third quarter.
"I hope that showed the nation today what kind of wide receivers we have.
