The ''problem'' is PK is huge on social media. He posts his stuff on a daily. I don't know if the rest of the hockey players are as active. With PK though it's not just showing some stories of him training or playing a game, it's that, then his love life, then it's video of him at an award show or gala or event, then a new restaurant, etc...
He shows it all so it looks like he's all over the place, but then, maybe others have a similar lifestyle they just don't advertise it.
That said, I do think his off-season trainings just aren't helping him. Never been a fan of them. This year he was better, he didn't do all the pointless track training he did the year prior, but still, doesn't seem like the optimal way to train.
