Because so many times I’ve seen those things happen. And the same two guys [Joey Logano, Denny Hamlin] involved in it are the same two culprits, but it came down to who had the most power, who could get in NASCAR’s ear the hardest, and they came down on us the hardest. It just disappoints me," Childress said on Dale Jr. Download.The team will surely have a huge burden off its shoulders now, having at least one of its drivers in the playoffs.
