Anyways, that hit was definitely to the back of Lyubushkin's body, which makes it worthy of a boarding call, but is it fair to say that Lyubushkin is the one who put himself in that position to be hit in the back?
You can clearly see him check over his shoulder to see Kolesar closing in on him, yet he still decided to turn his back to him. If it weren't for the front flip, I truly don't know if it would have been called a minor for boarding.
