I disagree completely.^^^^^ That's the whole crux of the matter you summed it up nicely. These rules limiting cup drivers in the trucks and Xfinity series were put into place to appease a loud and vocal wrongheaded majority of Kyle Busch haters. And I say that as a card carrying Kyle Busch hater myself.
No-one can point to any real evidence that Cup drivers competing in the lower tiers hurt anything about the sport. It's all a bunch of emotional meaningless BS used to keep Kyle Busch off the track. The lower tiers have been wussified and the competition made lesser.
Look at the Xfinity series a decade ago. You had a watered down Cup Lite with guys like Busch and Edwards and Keselowski winning everything. Compare that to last year, when you had a great battle between Bell, Reddick, and Custer. That never could have happened under the old format.
