I dislike both teams.
After reviewing the clip(lol), there's no way in hell that was a cheap hit. Unfortunately, there wasn't much either man could've done differently there. Markov was turning with his right skate, while his left skate appeared to be almost straight....so when he got hit, his right leg changed and he went straight into the boards, but it wasn't a hit from behind, it wasn't a cheap it.
As for the argument of him being chased, the clip wasn't long enough to show it. He connected more with his shoulder than Markovs back.
I didn't get a chance to watch the second clip, yet.
