WHAT GOES INTO A SEASON SWEEP AT A TRACK, IN PARTICULAR YOUR PERFORMANCE AT DOVER LAST YEAR? I DON'T KNOW, IS IT FAMILIARITY? IS IT MOMENTUM? IS IT PART LUCK? "We were lucky to sweep a track each year we've been in the sport. I don't know why. At times I've felt like tracks like Pocono, we've been able to do it there, even Martinsville, and Martinsville doesn't change a lot, so when you typically have something that works, it's going to last a while. Pocono is pretty close in time from the spring race to the fall race, so there's not a lot of time for the technology to change. But then we've won at Phoenix at the start of the year and the end of the year, and there's a lot that changes during that period of time. So I don't know if there's something consistent that takes place each situation. Dover is a fairly consistent racetrack, the concrete surface and things like that. But then we've raced on one tire in the spring and a different tire in the fall, so it kind of mixes it back up. I don't think there is a clear-cut answer. Maybe confidence has something to do with it; when you win the spring race, you have a good starting point with your setup to come back in the fall and you're very confident about what you're feeling and the direction the car is going."
