They had Mr. Helton in the TV booth yesterday before the Busch race started so that he could explain to us loyal TV viewers why the nationwide cars will run in the rain with “wet” tires, but the cup cars won’t. It took him about 5 minutes to explain it, and when he was done, I was more confused than before he started. The only thing he said that conveyed any actual communication value was when he said it was a “business decision.” But even that left me confused. Business decision? So what the heck does that mean?
