That P.K. would win the Norris isn't surprising in the least, he put up a season that was Chara level dominant, much more impressive than any other defenseman this season. What is surprising is that an NHL award would leak.
I don't think I'm going to confirm this as 100% yet, but it's quite possible that Subban has just earned himself a couple extra million dollars on his next contract.
Remember when Subban couldn't get respect from anyone? Ah the good old days. How ya like him now?
