Years ago, a certain crew, operating for Junior Johnson, replaced a blown engine during a race losing only 17 laps. That team won the championship that year, although they weren't the ones who were favored or expected to win. The NASCAR rules were changed before the next season disallowing complete engine changes.
There had been rule changes before whenever someone worked there asses off to gain a fair advantage. Known as "memorial rules", these were admittedly initiated to prevent "unfair advantages" purportedly aimed at the better funded teams, although several privateers were more often the real targets. But this time it was aimed at the previous year's Championship Team!!
The driver for that team went on to win another championship with another car owner, one who has repeatedly innovated himself into the establishment of even a few more "memorial rules".
NASCAR is becoming a namby-pamby, limp wristed, formula driven, caste system reserved for those who can pull down the most sponsorship money and most favor with the sanctioning body!!
I'm now evaluating whether I'll be following this "Entertainment" any longer!!!
