Which means we need more hockey players playing football growing up. Toughen em up, give em bite/edge, physicality, dawg, etc.
Give them early concussion problems more like.
Oh, and to answer OP's question, the game is changing, it's faster and more skill-based now so it's only natural that we see less power-types emerging.
But they are still there if you know where to look.
Carbonneau for example is a low-key physical player and a real pain to contain with the puck on his stick.
Sometimes I'll watch one of his games and Carbonneau will kind of show me flashes of Brad Marchand with his speed, doggedness, and ability to shield the puck, dangle and make plays.
But those flashes are unfortunately inconsistent. And the way Carbonneau is prone to bonehead plays as well as how he likes to rove all over the ice instead of playing a more traditional winger's position kind of give me pause as to whether or not he might have some deficiencies when it comes to his hockey-IQ.
Anyways, some other likely first-round prospects that could turn into physical players in the NHL one day include, in no order; Carbonneau, Martone, Martin, Smith, Spence, McQueen, Mrtka, Amico, Ryabkin, and others besides.
