I think had it gone green to finish or even to a very late caution, the good cars on long-runs with the primaries would have been in great shape. I think Larson, Blaney, Denny, and Buescher all had good long-run cars, but I think the 20 may have still had them covered. The 45 and 24 were really good too before their issues.
Would one of the long run cars gotten to the front on the primaries? Maybe. Or at least challenged the 20. But if a very late caution came out, you could have had a situation where the leaders had reds to put on but would have had to give up the lead to pit. That could have been a great - and a mess with some cars on old yellows and some cars on new reds. Yikes.
