First, I'd like to see the right side of Coulter's truck, because if Busch even touched him, it wasn't hard enough to leave a mark.
Second, Childress knew that Busch is on probation, and would get suspended for fighting.
Third, What could Busch have gained by this? Definitely a lose-lose for him. Hit and old man AND get suspended?
Lastly, would everyone, that are cheering Childress now, feel so good about it if he had been hurt? Another lose-lose for Busch, he's hated even more if he knocks Childress out. Imagine some 26 year old punk knocking out grandpa in the mall parking lot over a fender bender. Not quite as funny then, huh?
