I believe it, yes. I still think NASCAR makes a lot of governing mistakes, but I felt that they weren't going to let this one slip away after all the information that came out. Their initial comment was made immediately after the race before all the stuff came to light.
But their problems are still exposed with the fact that Bowyer gets away clean. No fine, no probation, no penalty. 50 points were docked before Chase reseeding so his starting position has not been altered. Gets away squeaky clean, with only reputation damage.
And Gordon was still unfairly screwed out of the Chase, and NASCAR did nothing to address that situation.
