Maybe, just maybe there's a possibility that Rantanen's low scoring at the end of the playoffs has to do with the fact the team wasn't playing well. They were losing puck battles, lack of depth scoring, ridiculous dump and chase style of play which doesn't work, clear lack of leadership which is reflected in case Hintz and the way people are underpefroming.
But Rantanen's "bust" wasn't the problem as he still was the best player in the team.
