I found their explanation of the debris caution interesting ... We had multiple reports from drivers, we confirmed it was a piece of metal, and before we could call the caution someone hit it. We are not sure what it was, or who hit it, but it was because of safety reasons that we called it. We had over 100 years of NASCAR experience in the tower, we were not playing favorites, it was because of safety that it was called, but they haven't brought the piece of debris to us yet. But it was confirmed debris on the racing groove. ...
Sounded like someone was protesting too much ...
