NASCAR fans, what do you think makes a good race car driver great?

I think a lot of it has to do with attitude.

Webster's New World Dictionary defines attitude as "A settled way of thinking or feeling typically reflected in a person's behavior."

There's obviously no shortage of attitude in NASCAR drivers, that's for sure.

Most of the drivers feel winning is the only thing, and second place is the first-place loser.

I once read bad attitudes make for bad ratings. I disagree.

Fans love to see the drivers get all fired up and go after each other.

I've never heard a race fan say anything about not wanting to watch racing because of a driver's bad attitude.

I think it's what helps drive the sport.

How boring would NASCAR be without the personalities of Kevin Harvick, Denny Hamlin, Brad Keselowski, Kyle Busch and Juan Montoya, to name a few?

Two drivers really stand out for me who have had huge attitude changes.

First is Tony Stewart.

Since he became a team owner he doesn't get upset as easily as he used to.

Although he hasn't been finishing races very well this year, he seems to constantly be trying to keep his attitude in check.

The second driver is Kyle Busch, who many of you know married Samantha Sarcinella on New Year's Eve.

This year his attitude is completely different.

In the past, if Kyle couldn't win the race, he would wreck the car. You know the old saying, "checkers or wreckers."

But I think since he is now a Camping World Truck Series owner and hoping to add a new team this year, he realizes a top-five finish is better than a wrecked car or truck.

Kyle is a great race-car driver. Being a business owner and a husband has changed him for the better, too, and that's not good news for the other drivers.

I say, watch out for this guy. He still has an attitude, but he's learned how to control it.

Attitude is good, but remember, it can make you or break you in any sport.

The Sprint Cup drivers are in Richmond Saturday night at 7:30 p.m. on FOX.
