News Analysis: Kyle Larson penalty costs him points lead

What happened: Kyle Larson’s team was hit with a significant penalty on Wednesday after NASCAR discovered an infraction during its post-race teardown following the Kentucky Speedway race. Larson crew chief Chad Johnston was suspended for three races and fined $75,000 while the team lost 35 points — this after NASCAR found the No. 42 team violated a rule that says: “Openings in the rear brake cooling hoses and/or tubes to exhaust air between the inlet and exhaust mounting points will not be permitted.”

What it means: Larson, who was up by one point over Martin Truex Jr. in the standings, is now 34 points out of the lead. That’s a big blow, because the regular season champion gets an additional 15 playoff points while second place gets 10. The difference between the two is the equivalent of a race win.

News value (scale of 1-10): Four. It’s noteworthy in that the penalty affects the regular season points battle, but there’s still enough time (eight races) for Larson to recover — especially with stage points in the mix. It would be a bigger deal if this occurred in the playoffs or if Larson had won the Kentucky race and the encumbered finish meant something.

Three questions: How much did this have to do with Larson’s impressive speed at Kentucky? If this was a performance advantage, will Larson now be slower in upcoming races? Will the points penalty itself turn out to play a role in the playoffs should Larson miss out on those five extra playoff points?
