Boykin's three touchdowns came against a scout team simulating "Boise State," in a practice game that was the third and final preseason scrimmage.
Georgia will play the real Boise State, No. 5 in the nation, in nine days in the Georgia Dome.
The "Boise" quarterbacks this time had "probably six picks in the game," coach Mark Richt said. "We cancelled a couple so we could get enough plays run by the defense."
The real Boise State quarterback Kellen Moore threw all of six interceptions last season.
"It was interception mania there for a minute," Richt said. The Boise State team was spotted a 31-0 lead to create a sense of urgency for Georgia's frontline players going up against mostly the scout team.
"Georgia made a dramatic comeback," Richt said. "The final drive of the game, scored a touchdown and won the game."
"We just came back and had a great second-half," quarterback Aaron Murray said with a laugh. "Just rolled right through them."
Murray completed 5 of 9 passes for 79 yards with no touchdowns or interceptions. Backup Hutson Mason was 7 of 9 for 98 yards and the touchdown.
Richt said he stopped one of Boykin's interception returns while he was en route to the end zone.
"I blew the whistle so we didn't pull a hamstring," Richt said.
`Strong runs' for Crowell
Freshman tailback Isaiah Crowell, who missed the last scrimmage with a sore groin, rushed for 54 yards and a touchdown on six carries.
Murray said Crowell had "strong runs. He looked really good." Junior Richard Samuel did not scrimmage because of his quadriceps injury.
"We still wanted to see what Harton would do and Ken," Richt said. "Harton I would say right now is our No. 3. Maybe after today we'll look at the film and see if Ken made up any ground on Malcome. I would still peg our running backs as Richard, Isaiah and Harton today."
Shawn Williams and Sanders Commings got the majority of the work as the starting safeties in the scrimmage, Boykin said, another indication that Bacarri Rambo may have lost his spot with the first group.
Commings, who started at cornerback last season, had an interception.
"He's just getting more comfortable with it," Boykin said. "He's pretty much ready to play on Saturday. …Even though Sanders moved to safety this year, he's right there where he needs to be in communicating."
Work still to do
Georgia still has to iron out some kinks, Richt said.
"We would not have been ready today," Richt said. "Even our pregame warm-up left a little bit to be desired. Got to iron that out a little bit."
End Abry Jones said the scout team's Boise looks were valuable. "As a defense, we kind of took this as our first real attempt to attack what Boise does on offense," said Jones, who had three tackles, including two sacks.
This and that
No players were injured in the scrimmage, Richt said. All players that missed the scrimmage with minor injuries are expected to play against Boise State including wide receivers Malcolm Mitchell (leg) and Marlon Brown (ankle), nose guard John Jenkins (hamstring) and fullback Bruce Figgins (hamstring). …The Georgia captains for the Boise State game: center Ben Jones, cornerback Brandon Boykin, end DeAngelo Tyson and punter Drew Butler. …Georgia cheerleaders, members of the pep band and mascot Hairy Dawg will be at a "Spirit Day" pep rally in advance of the Chick-fil-A Kickoff Game.
