Fuel only stop gives Hamlin the win

Denny Hamlin's crew took a chance with a fuel only stop on the last pit stop and it was enough to give him the win.  Obviously Hamlin didn't have the same trouble that we heard about from many drivers with forward bite.

Many drivers had problems, including the points leader going into the race.  Kyle Busch broke the rear end gear and finished laps down and dropped all the way to 5th in points.  Busch's drop and Jeff Burton's good finish put Burton in the points lead, with teammate Kevin Harvick 39 points behind in second.  I was actually surprised to see Harvick move up in points with the trouble he had, he was one of the ones that was having trouble with forward bite and basically grip overall, he definitely wasn't a Happy camper over the radio.

Aric Almirola obviously had a problem with grip also, since he seemed to have a problem not getting into other cars, he caused at least three cautions by spinning someone.

I'm not sure what Michael McDowell did, but Jeff Burton sure was mad about something he did, going by his post-race interview saying that the 00 needs to learn a  lesson or someone will have to teach him a lesson.  Anyone know what McDowell did?  I obviously missed it, I'm assuming he was in the way or something, but I'm not sure.
