Norwood and Cooper's six-point plays sandwiched a second score for Lacy, this time from 1 yard out.
The bruising back amassed triple-digits in just 30 minutes and concluded the contest with 131 rushing yards and the two touchdowns on 18 carries.
McCarron made the most of his only second-half appearance, capping off the Tide's first drive of the third quarter with his fourth and final score, a perfectly placed 38-yard beauty to Norwood.
The quarterback completed 15 of 21 passes for 216 yards. Cooper and Norwood both accounted for five receptions and two touchdowns, but the former edged the latter in yardage, 109-65.
Alabama's defense was every bit as masterful as its counterpart in the unit's fourth shutout of the season. Robert Lester and HaHa Clinton-Dix both had interceptions, while Nico Johnson forced a fumble that Dee Milliner managed to scoop up.
After failing to meet the team's goal of picking up at least three turnovers a game the last couple of weeks, Johnson was pretty psyched about the Tide D reaching that total on Saturday.
“I feel like when we create turnovers and everybody is flying around and hitting and knocking the ball off people, then we're having fun,” he said.
From McCarron to Lacy to Cooper to the D, Saban couldn't pick just one player who stood out more than the others.
“I think this is a great team victory, how everybody sort of contributed,” he said. “We asked everybody to play their best game today. When you make a commitment to something, it really comes from the heart, and I really thought our players did a good job of that.”
The disastrous defeat epitomized Auburn's 2012 campaign, which proved to be a far cry from the Cam Newton-led 2010 version that brought the school its second national championship.
