I love Clifford but he really didn't land anything in this fight. I was 6 rows away and Carcillo started out the fight with two huge bombs. I give Clifford credit for not going down. He is a big strong kid.
The camera view and the ref blocking it make it look like Clifford knocked Carcillo down but all he really did was pull his jersy up and punch him on the shoulder then shove him down while Carcillo was off balance.
The camera showed the entire fight the second time. I'd wager Carcillo didn't even land one punch even at the beginning. All he did was glance off the shoulder pad and opened himself up in the process.
