Long story short, Truex started at the rear of the field, due to some issue during "tech inspection". He patiently and skillfully worked his way up to second place, and then CLEANLY passed Logano with a couple of laps to go. Logano then "did what he had to do", as they now call it, and dumped Truex, as they entered turn 4, on the final lap. Logano "won", or should I say crossed the finish line first. Truex recovered, but still got nipped to the line by Denny Hamlin.
Logano, in the post race interview, is all beaming, crowing that he's going to Miami. Truex, in his interview said, "He WON'T be the champion, I assure you".....
Personally, I think that Truex should "hire" Matt Kenseth, to administer a little payback.
