Theyre both determined player that play gritty games and leave it all on the ice. Kotkaniemi is literally a defensive specialist that plays physical at this point, unsure how hes not a high character player.
High character players for me is not someone who plays well defensively or are physical. In fact it doesn’t have nothing do to with there game
It‘s more how they have the drive to be the best player possible, how hard they compete, how they react to critics, how they handle failure , how they will do everything they can to win games, how they can quickly forget a mistake, how they will make every sacrifice, how he treats people around him and put the team in front of his personal success
It’s more a personality thing that you have in you. Best exemple is Cole Caufield that I do consider as a high character player.
