After colliding twice midway through Sunday's Subway 500 at Martinsville Speedway, Matt Kenseth and Carl Edwards seemed to put the incident behind them with a chat over their in-car radios.
Kenseth, though, wasn't very surprised when Edwards accosted him shortly after the race.
"His behavior has been real erratic lately, honestly," Kenseth said of his Roush Fenway Racing teammate. "You don't know what to expect with him. That's the thing that's a little bit troublesome. One minute, he has so much respect for you, and he's real friendly and everything's so much fun. The next minute he wants to kick your butt and he's swearing at you. It's a little scary. You never know what you're going to get.
"I thought it was good in a way that the cameras were there because a lot of us see that, and nobody else does because he kind of puts on a different front."
