Kenseth's comments on his and Edwards altercation

I'm sure by now everyone heard about the little altercation between Kenseth and Edwards after last weeks race. 

Edwards apologized on Tuesday for the incident, saying he shouldn't have shown his anger towards Kenseth, but that trouble had been brewing between them for a while.

Yesterday, Kenseth made a statement about the whole thing -

His behavior has been real erratic lately, honestly. 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 everythings 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.

Most of what the fans see is a happy-go-lucky guy, he always smiles in his interview and of course he has his trademark backflip when he wins. 

If we are to believe Kenseth, there seems to be two sides of Edwards, kind of like Jekyll and Hyde.  Whatever problems exist over there, Roush obviously needs to step in and help them work it out, I know that he usually lets everyone work things out themselves, but it just doesn't seem like these two getting along and won't any time soon.
