Kyle Busch Called Himself a "Genius" After Greg Biffle's Final NASCAR Win

It had been 15 years since Greg Biffle had competed in a NASCAR Truck Series event, but at the 400 at Texas Motor Speedway on June 7, 2019, Biffle raced his way to the checkered flag, showing that the former Truck Series Rookie of the Year could still get it done on the racetrack.

Biffle drove the No. 51 Toyota for Kyle Busch Motorsports, which is obviously owned by the Kyle Busch, the extremely skilled and equally outspoken NASCAR driver. Following Biffle's big win, Busch, in his typical fashion, decided to pat himself on the back and take a little bit of credit for Biffle's victorious comeback.

Differing from Busch's cocky tone (though you have to believe it was more tongue-in-cheek than anything), Biffle was humble and appreciative following his success at Texas.

"I am just excited to be here. I don't even know what to say," Biffle said, according to ESPN. "I am so thankful for all the opportunities I have had to drive great trucks. This thing was really fast. It was hard to figure out how to pass here. It was my first time with this [aerodynamic] package, so it took me a little bit, but I got used to it in the end."

"It was not easy. I had my work cut out for me," Biffle said. "At the beginning of the race, so much odd stuff happened. We ran five laps at a time and then the caution would come out. There was a lot of people wrecking in front of me and behind me. I was just trying to keep the truck clean and stay out of trouble."

Biffle, who won the Truck Series championship in 2000, has 56 wins across all three national NASCAR series — 19 in the Cup Series, 20 in the Xfinity Series, and 17 in the Truck Series. Other major accolades include the 1998 Truck Series Rookie of the Year award, the 2000 Truck Series Most Popular Driver award, the 2001 Busch Series Rookie of the Year award, and the 2002 Busch Series Most Popular Driver award.

Biffle's Texas win was a more positive change of pace for the NASCAR driver, considering the last major headline involving him stemmed from a lawsuit filed by his ex-wife, Nicole Lunders Biffle, over claims that he had secretly recorded her. A jury eventually found that Biffle committed an "unlawful invasion of privacy," and he was later ordered to pay Lunders $250,000.

Earlier this year, Biffle has another big NASCAR return, albeit a much less ceremonious one. After a six-year hiatus from the NASCAR Cup Series, the 52-year-old Biffle raced in several events for NY Racing Team. Driving the No. 44 Chevy, he placed 36th at the Daytona 500, 34th at Las Vegas, 20th at Atlanta, 37th at Richmond, and 35th at Talladega.
