Tournament success is team based and electronic had s1mple on his team to carry all of his tournament wins.
Meanwhile NAF is the best player on his team and was individually better than electronic this year. He performed at an EVP level at more events.
Maybe if electronic had gotten an MVP at one of thos big events he would be potentially higher but all of the tournaments that navi won are due to s1mple going God mode and carrying them thru matches they didnt deserve to win or the infamous Zeus 30 bomb vs astralis at Cologne.
When you compare the two players individually NAF has more MVPs, more EVPs, a higher peak, higher ADR, Impact and rating. Of course he will appear higher.
Unless you can name any instances in which a player had less in all 5 of those things while being on a top 5 team and not been placed above a player with "more tournament wins"
