Marchand's not a bad guy, but he saw the hit coming and a real man braces himself and gives it right back. Clipping is taking the easy way out. Anyone can do that. There's nothing impressive or brave or admirable about what Marchand did. He just took the easiest option.
Before anyone else even chimes in with the thought too - Marchand didn't NEED to do this to protect himself, but if Salo wasn't so determined in creaming him, he could have moved or gotten low as well... He only got "clipped" because he was trying and determined to make a high hit...
Ducking down and clipping when an opponent comes in for a legal body-check is two things:
I'm sure Brad regrets this decision. He's got too much respect for the game to repeat this crap.
