„I think that, I don’t know. I’ve been on multiple sides of it where you know, the Xfinity year is a great example. We won nine races that year. I finished fourth in the championship. Like, I think Justin Haley won Talladega, and he finished second or third in the championship. Like, I don’t know if that was right, but he performed better in that race than what we did,“ he added.
