A NASCAR team boss has called for a major shakeup of the playoff system, while acknowledging that the single-race championship system was a 'good experiment' when it was introduced.

Trackhouse Racing owner Justin Marks appeared on SiriusXM NASCAR Radio this week to discuss his thoughts on the impending changes to NASCAR's playoffs, whatever they may be.

The accepted wisdom at this point is that next year will not see a champion decided by a single race at the end of the season, but officials and the playoff committee are yet to settle on their favored alternative.

Marks likened NASCAR to other sports, pointing out that boiling the season down to one final event doesn't always make the Super Bowl an exciting game, and that not every World Series ends in an extra-innings Game 7 as this year's did.

Marks: One-race showdown was good experiment

He explained: “You have to balance what’s required in the world today to be an entertainment property that gets people excited with the fact that you are running a sport.

"When you run a sport, you just aren’t, you’re not going to have those game five buzzer beater moments, those bottom of ninth home run World Series moments every single time you go. I mean, we talk about this a lot, like some years the Super Bowl is a one-possession game with two minutes left, and some years it’s a blowout."

He continued: “I think that the one race final championship was worth trying. I really do. It was a very transitional time in the history of NASCAR. I think it was a good experiment.

“I don’t think that’s the right thing for the future. There is a balance between the final and 36 full races. But I think that the last race, the champion needs to be crowned by the person that performs the best over the course of the season.

“Now I know that sounds like me saying 36 races. I think a playoff thing is important, and it’s important to sort of build excitement towards the end. But I don’t think it is good for the sport not to take anything about five, eleven, whatever. I really just don’t. So I think there’s a balance there.”
