Have to give it to Mike Richards, actually. I thought it was clean, even though the shoulder did hit the head . . . but we are talking about carrying the puck over the blueline on a dangerous rush - so a solid hockey play. I voted based on how crucial a hockey play it was.
Ovechkin's was second for me . . . and totally clean, clearly hit him on the side, not sure why he was penalised AND ejected. I could see a marginal charging call . . . but really, it's just three strides or so and no elevation - just a solid check from a solid player.
