Honestly, I can see what NASCAR's motivation was and applaud them for taking action to 'set things right'. However, (and I was pretty steadfast in this) I thought it was wrong for them to retroactively add/remove drivers from the chase in the first place. By doing so, NASCAR played revisionist history and opened up alot of what-ifs; are we certain that Ryan Newman wouldve won the race with 9 laps to go? or that Martin Truex wouldnt have raced his way in anyways? In going back and revising the standings based on the richmond race, NASCAR complete disrespected the results of the actual racing itself.
I was of the opinion that they shouldve kept the chase field as the race results dictated it, but shouldve punished MWR and Penske AFTER the points reset (levying heavy-a** penalties too, like 100 point deductions from all the MWR cars and Penske cars). That way, the results of the race are respected and preserved, and at the same time, you've set a HEAVY deterrent by effectively knocking all the cheater cars out of contention.
EDIT: my proposal might not be the most popular one because it means that ryan newman misses the chase in this scenario, but who's to say he doesnt cut down a tire with 3 to go?
