These drivers didn't have their careers cut short, but chose not to get into Nascar. Drivers like Larry Phillips, Bob Senneker, Mike Eddy, Tom Reffner, and others. And Trickle who got into Nascar late. From what I understand, they were making more money hitting the big local shows back in the 70's and 80's. I wonder how Ed Howe would have done as Nascar builder/innovator (he was a pretty good driver too)?
