ATHENS, Ga. -- New Mexico State coach DeWayne Walker was nearly speechless trying to describe what he had just witnessed.
"We're better than that score," he said after the Aggies lost 63-16 to No. 18 Georgia on Saturday. "We just picked the wrong day to not play well. I guess obviously [Georgia] needed to make a statement, so we're just going to go back and get ourselves ready for next week."
Aaron Murray threw five second-quarter touchdown passes and former walk-on receiver Brandon Harton ran for 98 yards in Georgia's seventh consecutive win.
The Bulldogs (7-2) turned to Harton this week after Isaiah Crowell and Carlton Thomas were suspended one game for failing a drug test. Georgia was also without No. 2 tailback Richard Samuel, who will miss the next month after undergoing ankle surgery.
"Against teams like this, you have to play perfect the whole game, and it still might not be good enough," Walker said. "But I just know we should've played a good football team better."
Kenny Turner scored both New Mexico State touchdowns, the first on a 10-yard run early in the fourth quarter that made it 56-10. The Aggies (3-6) have lost three straight.
Aggies quarterback Matt Christian was knocked out of the game with an undisclosed injury as he tried to tackle Baccari Rambo on the Georgia safety's 51-yard interception return late in the second quarter.
"He made the wrong read, and they made a play," Walker said. "He's a tough guy and he tried to get in there and make a play. He kind of got himself dinged up a little bit."
Aggies freshman Travaughan Colwell was 8-of-12 passing for 120 yards and one TD in the second half. Christian completed 12 of 24 passes for 156 yards and the pick.
"Everybody had us picked to only win one game this year, and we've got three and still have four games left," Walker said. "We've proved the oddsmakers wrong already, but I'd sure like to add a couple of more wins before the season ends."
Murray, who played only the first half, completed 18 of 23 passes for 238 yards, five TDs and no interceptions.
The Bulldogs hadn't scored 63 points since beating Northeast Louisiana in 1994, seven seasons before Mark Richt's first year as head coach.
Georgia's 627 yards on offense was its most since a '93 game against Southern Mississippi. Nine Bulldogs scored touchdowns.
"They did what I asked them to do, what our coaches asked them to do," Richt said. "And now we get an opportunity to relax a little bit, enjoy the rest of the day and watch the big ballgame tonight and hope Arkansas wins."
Harton had not taken a snap since the Bulldogs' blowout win over Coastal Carolina on Sept. 17. He lost a fumble on his first carry, a 9-yard run to the Aggies' 3, before redeeming himself with a 4-yard TD run to make it 14-3 early in the second.
Cornerback Branden Smith, who occasionally plays offense, started at tailback and made it 7-0 with a 56-yard touchdown run midway through the first quarter.
Tyler Stampler's 24-yard field goal early in the second helped the Aggies cut the lead to 7-3, but Georgia scored touchdowns on its next six possessions to take a 49-3 halftime lead.
Walker praised Turner, who ran for 101 yards on 23 carries and caught eight passes for 127 yards, and the coach likewise was pleased with receivers Austin Franklin and Taveon Rogers.
"There's going to be some guys -- and that's what I really want to look at [on video] tomorrow -- that fought all the way through," Walker said. "That's what I want to look at and see."
