LOL. Rich and his staff run a ton of cars all day. They pick an ET range. Then they pick 8 cars within that ET range. And you're going to try to tell me they have no idea which car should win?

They pick a winner, and then run the race. They pick 8 cars in a given ET range, and you think one of those cars isn't faster than the rest,

and you think they don't know

? If you don't think they pick a winner before the race, I can't help you. They may not get the winner they want, their chosen one might be late, he might go red, or he might break. But he is their chosen winner, regardless. And if he doesn't win, they start asking questions and getting pissed.
I've sat in the toter after the races and watched that contrived BS dozens of times, I've watched Rich and his boys pick out their chosen few, and their chosen winner. Then I've watched them be stunned when it doesn't work out the way they planned.
You can run all of their races you want, it doesn't bother me one bit, I really don't care what you do or what you believe. But I know a scripted "show" set up for TV "drama" when I see it.
