This is true, but in that case the guy with the most money, usually wins, they needed to make the show appealing to everybody.
As far as bracket racing goes, this is a heads up style format, not bracket racing. I've never gotten out the beams in a street race, not that I've ever street raced. ;)
I would also assume no Mopars run Pinks due to the cost of builds, anymore all you see are shop cars out there. I can build a Fox body Mustang for dirt cheap and it'll run 10's all day long. Not so with my Mopar, but I'm going a different route with that car anyway.
