While his drivers are friends and teammates, Gibbs said he expects some of that to wear off when February arrives.
"I was thinking this whole offseason they got along great and everything, but that's going to last until about the first time they get alongside each other up front," Gibbs said. "And I'm going to be ducking and dodging. All of these guys driving for us, we know each one is going to be going after (a championship)."
The good-natured jabs heated up at Thursday's Sprint Cup Series media day.
While on stage with his teammates, Busch was asked when Hamlin will get to sign a long-term extension with JGR.
"Well, we already gave him all of the best stuff," Busch cracked. "He had the fastest Toyota car down at Daytona in testing. What else do we gotta do? He's already got all of the good stuff."
Hamlin jabbed back, "I make up for it in talent."
Hamlin admittedly is a little sleep-deprived of late. He and his longtime girlfriend, Jordan Fish, welcomed their first child, a daughter named Taylor James Hamlin, born on Jan. 20 at 8:20 p.m. (20:20 military time) and she was 20 inches long.
"We squelched the rumor that Denny will now be driving the No. 20 car," joked JGR president J.D. Gibbs.
Kenseth brings a winning resume to Gibbs Racing. A two-time Daytona 500 winner and the 2003 Sprint Cup champion, Kenseth has won 24 Cup races including three last year for Roush Fenway Racing.
"It sounds like Kyle and Denny are already tied for the championship this year, but I'm looking forward to this anyway," Kenseth joked as he looked over at his teammates. He called it a "new beginning" and said sometimes change is good.
"I feel like it's a great opportunity to go and hopefully compete for some wins and try to compete for a championship," Kenseth said.
Said Gibbs: "It's great having Matt on board. He's somebody that we all respect. It's a thrill for us to have him."
