Have absolutely zero intention to single you out, but I do see comments similar to this all the time. I'm no fitness expert but different players thrive with different builds. Buch relies more on shiftiness and maneuverability and as such his slender physique is probably advantageous to him. Definitely needs to bulk up a little bit but surely there has to a limit. Kreider, on the other hand, I don't classify as shifty in the least bit. For as fast as he is, I think his build limits him in ways in that he can't dance around players with the ease that you might expect. Is why he's really only effective as a North-South player. Just my opinion.
