You have to ask yourself if this "bad boy" McKinne fit in to the locker room with certain guys so well that it was the last mental straw for Martin, to see someone getting along with guys better than he was after all His (Martin's) work to improve and fit in. Like he was not going to be out of the position and get bullied, while watching some new dude getting along so easily.
Wait for it.
Wait for it.
