The majority of those rules changes pale in comparsion to the drastic and frequent changes NASCAR makes on a yearly basis. Imagine if the NFL made rules changes every couple years to add a 5th down, make it 9 on 9, and add a 4 point field goal. Then you could argue it's similar in nature to the changes NASCAR has made.
Also, except for the NHL, the majority of those changes suck. The NFL and MLB were better back then.
Also also, NASCAR is nothing like stick and ball sports.
You are correct in that NASCAR is nothing like stick and ball sports. That's why they can make more drastic changes to their product. NASCAR is governed just like a stick and ball sports and deal with many of the same problems with ratings, attendance, sponsorship, and tv deals making other things. I agree NFL and MLB were better back then but you have to deal with change. MLB is not going to allow steroids again and the NFL will continue to be the no fun league.
