William Byron and crew chief Rudy Fugle barking at each other about the handling of the 24 car just before the rain delay. This was around Lap 90
"Plowing my ass off. This is terrible!"
"I fucking heard you, OK!? I heard you! I got it! You're five numbers loose, I put a round in the left rear, we're too tight right now! It's the tight offset! We can park it, or we can keep trying until I get to work on it again! Just drive the fucking thing!"
"You got it!"
Keep in mind that William and Rudy have been together for a long time
