Who says Hischier doesn't outmuscle players? Have you even watched his tape or read scouting reports? He's a very strong player and is effective in the dirty areas of the ice.
Very strong? Com'on dude, first off, yes I have seen his tape and read his reports and neither suggest or say he's very strong and I don't think it's all that important that he does at this moment or that he be the strongest player on the ice.
Second, if there is one constant in those reports on the con side is that he needs to add muscle, some even suggest he's not the strongest player on the ice but like I said, he doesn't need to be, it's not what he will bring to that ice or is it important that he does like it is for Patrick.
BUT is a battler and will fight for the puck, but don't confuse that with being very strong or suggest Nico is on par with Crosby when it comes to strength.
Be fair when analyzing these kids upside and downside, not stretch like suggesting Patrick is comparable to Schenn or Nico to Crosby. There are going to be some areas Patrick is better than Nico at and vice versa.
