Well, ya gotta catch em before you can bump em!!!! I think Jr. was smart enough to remember that the big bump and run out of turn 4 on a superspeedway usually takes out the bumper and the bumpee!!!! With Jr. pushing on Biffle they couldn't close on Kenseth. Maybe that lower spoiler on the rear lets enough air down off the back of the car to slow the rear car down unless he's ready to drag the brake, back off, and take a run at the leader.... Kenseth definitely had both Biffle and Jr. out horsepowered on the last couple laps! That, along with whatever the air is doing now with the changed aero package on the rear on the rear of the car pretty much sealed the win for Kenseth! I'm sure that Jack had also mentioned to both Biffle and Kenseth that he didn't want to see 2 of his cars pounding on each other for the win!!!! Kenseth had the car, the power, and the crew all week!! Sure was good to see the Ford's win another one at Daytona, I'll say that! Roush ended up with 1st, 3rd, and 8th, not a bad speedweek for the Cat in the Hat!
