Like a new muscle car that replaces the classic hot rod, sometimes, change is good.

Georgia’s latest souped-up machine is built with a chassis matching its older model’s speed and power, a terrifying truth for opposing defenses.

And inside the glove box there’s an extended warranty guaranteeing at least two more SEC seasons with plenty of races left in the tank.

They don’t make many like Nick Chubb, a true freshman who did it again over the weekend, cruising down the fast track at Arkansas with 202 yards and a couple of touchdowns during his team’s fifth straight victory.

The kid’s looked indestructible in two starts during Todd Gurley’s indefinite suspension, becoming the go-to player on offense thought to be void of someone who could replace, much less exceed, Gurley’s production.

Talk about a luxury for coach Mark Richt, walking into a showroom with his choice of talented running backs despite a couple still in the shop. Chubb’s separated himself from the rest of the lot, carrying the football 68 times in Georgia’s last two games with barely any time to stop and re-fuel.

With just a couple scratches, he’s come through early and late for the Eastern Division frontrunners.

“He’s taken the majority of the carries and it doesn’t seem to phase him,” quarterback Hutson Mason said. “The guy’s a special cat. He’s got to be the best freshman running back in the country. You give it to him 20 or 40 times and it just seems like he’s going to keep pounding it. It’s awesome.”

Chubb will need to keep it up for the duration of the regular season if Georgia’s unexpected journey to the College Football Playoff after a loss at South Carolina in Week 3 comes to fruition.

The Bulldogs first pulled the cover off during the opener against Clemson when Chubb broke three tackles and lost his helmet on a 16-yard gain. He finished with 70 yards including a 47-yard gallop to the end zone when he hit another cylinder after reaching the second level.

The Chubb Factor was born.

“When he hits you, he’s got some pop to it,” ESPN’s Todd Blackledge said during the broadcast. “And he’s hard to bring down. He runs with great leverage and a low center of gravity.”

At the time, Gurley was the daily driver for the SEC’s top rushing offense, but heading into the bye week nearly two months later, the early Heisman candidate’s an afterthought as Georgia’s season nears its defining moments.

There’s a chance Sony Michel and Keith Marshall could return for the rivalry game with Florida next weekend for added depth. And even if Gurley’s reinstated and able to play, rest assured Chubb’s workload won’t change much. He’ll still get a fair helping of touches.

Could high-mileage become an issue for the Bulldogs’ dream car down the stretch?

“We keep an eye on (Nick) throughout the game,” Richt said after the Arkansas win. “We didn’t run that many offensive plays. We didn’t feel like we were wearing him out. If you watch him and his body language he did look tired, but he didn’t look tired with the ball in his hands.”
