That was an unnecessary caution. I think Nascar could have waited a few more section after Briscoe spun out because he went down and was out of the way and then Larson was almost to the white flag and the race could have been over. Too many cars got wrecked after that next restart. I guess the guy pushing the yellow caution light button didn't learn from last time about calling the caution too soon. Dillon certainly surprised everyone at the end too.
I had to watch the shortened version at 4am so I'm sure missed a lot of commentary and all the after race interviews but do agree that they need to talk to the guy who has the trigger finger on the caution button!! LIFE may be like a box of chocolates, but not Dale Jr. With him, you always know what you are getting!
