Well, if anybody doubts Logano did it on purpose (and can see past Jimmy Spencer's tyrade), the radio snippet in this may change a view or two.

I wouldn't listen to that moron's perspective if it was going to pay the bills for the rest of my life. Jimmy Spencer is the same person that back in 04 claimed Dale Junior was cheating due to how many super speedway plate races he was winning, and how many great finishes he was getting that year alone. At the end of the day, yet again I must say this. Joey did not do the wreck on purpose you can see that from how the car came off of turn three to four. Joey is just pandering to the media (originally) and acting tough due to Hamlin wrecking via hard racing. Basically he didn't wreck him on purpose, but wants to look like a tough guy to all others that might think to bully him. We will most likely see Stewart wreck him and that I can assure you will be on purpose.
Him pretending to be some tough guy and say "Yeah I got him" due to a cause and effect of hard racing I find asinine. The only video that should really settle this is an in car, or above view, not some snippets of radio talk or interview...that's just tough guy BS.
EDIT: Also since Spencer never makes much sense, he got something else wrong. There was clear radio message from Joey and in car view of him shutting the car on and off to cool it down. Joey knew the car was going to blow, the way Spencer puts it is wrong in saying "you didn't know your car was blowing up". It's the end of the race, you're in the lead and the engine needs to be reworked either way, so it is ideal to run it hard because if you don't you just purposely gave up the win in a car that is going to be different, next weekend.
Also Denny has an issue, with spatial awareness it would seem. Like when blaming Austin Dillion last year saying he pushed him down, when clearly the 43 and Dillon's 3 were have a close battle and Dillion had to go low didn't see Hamlin. But Denny didn't care and like usual thought he was under fire, just like he did at Bristol two weeks ago, thus angering another driver. Yet let's put political correctness spin on the situation and not bring Denny's faults to light because of his situation...
