^ I was not aware of that "top 50" rule, and it wouldn't seem right if Regan Smith showed up with his own car and wanted to enter the All Star weekend. However, Richard Petty Motorsports is a legitimate entrant, and they have a car built, sponsorship arranged, etc. It makes perfect sense to me that they can hire whoever they want to drive it (subject to some minimum Cup experience, which Smith does possess).
Still, it is a boring, uninteresting choice. I hope Biffle or Bubba is in the car for the World 600 and beyond. JMO.
