this is Burton's last year at RCR. That leaves two open seats at RCR. I don't think the third seat is an issue because I don't believe billionaire John Menard has a problem with writing a $20 million dollar a year check for his son to to have a ride in Cup with RCR plus it's a business expensive. Comes out of Menard's Home Improvement stores advertising budget. The oldest grandson, Austin, isn't lighting the world on fire this year in the Nationwide Series so Grandpa Richard might not be ready to move Austin to Cup next year. I believe the youngest grandson, Ty, is 2 or 3 years from Cup. There's plenty of room at RCR for Newman or Busch, but probably not both, and let's not forget if Richard Childress can get sponsorship, or if someone can bring sponsorship $$$$ I'm sure there's room for a 4th car at RCR.
