Yes he was leading. Car behind him got loose and got into him which turned him into the wall. Just a racing incident.
It's scary when you wreck at the front of the field, you hold on tight hoping people she the wreck and avoid you.
I will add that Newman was blocking for the win, and then car racing happened. It is purely a racing incident and no one was at fault.
I get they had a few hundred yards to go to the finish line, but with it being at the front of the pack if they should have thrown the caution, that said, there was no avoiding him, and it wouldn't have mattered had they thrown it. I more selfishly didn't want Hamlin to win again. I was really hoping Newman could hold on. Most of that went out the window when Newman's car went upside down and go T-Boned but if they froze the field Blaney would have won, and that would have been okay with me.
