up Vanderbilt's first touchdown. Walsh missed a couple of fieldgoal attempts before finally making his third. Stafford was intercepted twice.
"You really can't shoot yourself in the foot, especially down there in the red zone," Moreno said.
Mackenzi Adams, who replaced Chris Nickson as Vandy's starting quarterback this week, threw a pair of touchdown pass to Jamie Graham.
The Commodores (5-2, 3-2) lost their second in a row, again missing a chance to become bowl-eligible for the first time since 1982. They have five more chances.
"Our guys don't quit," coach Bobby Johnson said. "I don't even have to worry about them. I think we played better this week than last," an ugly 17-14 loss at Mississippi State.
Moreno had his fourth 100yard performance of the season, which included an 11-yard touchdown run. Green went over 100 yards receiving for the second time in his college career, scoring Georgia's first TD on a 17-yard pass.
Johnson decided to go with Adams at quarterback in hopes of beefing up the passing game. The new starter was 16 of 32 for 131 yards, with two interceptions. Nickson got in for one play, fumbling a snap on third-and-1 near midfield.
Walsh missed a 40-yard field goal on Georgia's first possession, then clanked a 37-yarder off the right upright late in the game.
"I thought when the ball hit the upright and came back, it was a good omen for us," Johnson said.
But Vanderbilt's last chance ended when a fourth-down pass from Adams to Graham came up a half-yard short, stopped by a big lick from Asher Allen. Georgia took over, ran the clock down and Walsh finally kicked one between the uprights.
Stafford and Green got rolling on the Georgia's second possession. The freshman slipped behind the secondary and hauled in a 49-yard pass over the shoulder. Two plays later, Green made a leaping catch for a 17-yard touchdown, the 6-foot-4 receiver going up to get the ball over 5-10 cornerback D.J. Moore.
Georgia made it 14-0 late in the first half, the drive beginning after Darius Dewberry picked off Adams. Moreno broke off two runs totaling 33 yards, Stafford hooked up with Green on a 13yard pass and Mohamed Massaquoi got free in the back of the end zone for a 9-yard touchdown catch.
Vanderbilt responded with an eight-play, 75-yard drive just before halftime. Two pass interference penalties -- one a disputed call on Allen, the other a more clear-cut violation on Bryan Evans -- pushed the Commodores deep into Georgia territory. Adams threw it up in the corner of the end zone and watched Graham out-jump Evans for an 18yard touchdown.
The Bulldogs seemed on the verge of putting away the Commodores when they marched right down the field on the first drive of the second half. Moreno had a 19-yard run, Stafford went to Green for a 33-yard gain and Moreno scored from the 11, after an apparent TD was overturned when the replay showed the runner's left knee was down.
Again, the Commodores bounced back. This time, they took advantage of Stafford's second interception, a pass that was tipped at the line and grabbed by cornerback Myron Lewis at the Georgia 26.
Vandy scored with a nearly identical play as its first TD. Adams threw into the left corner for Graham, who pulled it down over Evans for an 8-yard score.
"We stalled out on offense a couple of times," Stafford said. "But we battled. I'm proud of the guys."
Before the start of the fourth quarter, Georgia coach Mark Richt gathered the players around him to make sure they knew what was at stake. The Bulldogs, who started the season No. 1, couldn't afford another conference loss if they wanted to keep pace in the SEC East. They're tied with Florida for first place and still in contention for a national title.
