I watched the RV pass on JS under yellow a few times and to me it looked like they were all on the brakes, but JS slowed down more and RV slid right by him into the turn. Not sure how RV could have avoided passing him really... its not like he had the throttle pegged or anything.
Awesome race though... that's more action than we've seen all year. I was hoping to see another RV/JS battle, and this time RV won it. JS is definitely looking fast though!
