McDavid is clearly the best skater in the league and has the best hands, he is big and athletic, if he was also the smartest player in the league he would’ve separated himself from other players in the league by a even bigger margin, it would be like Gretzky on rocket skates.
Aho wasn’t a good skater in Liiga, even less so in the NHL, he doesn’t have a great shot and he isn’t strong or big and doesn’t possess puck skills like Kane or Datsuyk, and yet he is one of the top centers in the league without having any standout physical attributes, only reason he is so effective is his brain, his nickname has been ”Proffesor Aho” for a while.
