I mean really, when Hamlin made the move to try to pass Logano and Dillon he was taking a chance that he would be able to pass them clean. There was no guarantee that he would get by them clean. After watching the replay of what happened it looks like Dillon went back down to block Hamlin but Hamlin also had moved up after the turn and then he got turned. Hamlin didn't stay completely on the bottom. So to me there isn't even a clear and obvious intent by Dillon to spinning Hamlin on purpose, even if Austin did intend to do it.
