Man, I am not sure we all watched the same thing.
What I saw
1. AJ had the line when he got under him. They made contact. It wasn't anything egregious.
2. Chastain had a huge run when he got behind Allmendinger and Bowman went to the oustide. He kept it in the gas for his momentum, all while giving AJ a shove that he knew AJ would have to slow down for.
I don't think Chastain was attempting to dump dinger as much as he was just forcing him into a corner at a high speed. Dinger almost saved it before he pancaked Bowman and spun around. Maybe AJ saves it if Bowman isn't there, maybe not. But in all the years I've been watching racing on all levels, this was on the weakest levels of a bad dump/wreck.
I listen to a lot of radio during the day...and Dave Moody constantly complains that "rubbin isn't racin"
yet the drivers say it is. I saw some rubbin. I saw some racing. And I thought all 3 shows this weekend were decent.
