Subban had 2 main issues contributing to his downfall...
1) he got hit by his teammate Emelin in Montreal even before the trade to Nashville, and I don't think the injury he sustained to his back ever really got resolved. It wasn't bad enough (at the time) that the trade was ever called into question. But it definitely seemed to be a contributing factor to his subsequent rapid decline.
2) He didn't train "smart". Subban had a relatively small build for an NHL defenseman, and he simply overcompensated with the weight training regime he undertook. He had great edgework, mediocre speed before things went off the rails. But he thought he needed to be Bigger, Stronger, and he kind of seemed to take on a training regime that promoted bulk strength? Which is always going to be a dumb approach for NHL hockey. You need other quick-twitch and isometric type training for the modern NHL, bulk strength alone really doesn't cut it. He should have tried to stay fast and mobile, instead he got bulky and slow.
I think it's unfortunate, because Subban had such an electric on-ice presence, he could have been a #1D on many teams, and a perennial Norris candidate. The thing that stood out on Nashville was just how much he WANTED to win. He was awesome on a pairing with Ekholm, I thought he was our #1D easily. He battled so hard despite his physical limitations. Ultimately, I think Roman Josi even learned a little bit from Subban about trying to maximize his skill, and it paid of for Josi's numbers afterwards. I still think Subban was the superior player, based on his combativeness and ability to step up in the playoffs. But Josi took some of PK's attitude to heart and subsequently elevated his game (offensively anyway) after PK left.
I thought Subban would transition a little more smoothly into the off-ice role? I guess he's "there" now on your TV broadcasts, and some people like him and many don't, but I honestly thought he'd have "conquered" the media role a little better by now?
Anyway, I thought he was an "underrated" player for Nashville, as a player, and I wish he could have played longer. But he obviously had different priorities, sensible priorities, off the ice, so be it.
