Players are better these days. But he got 2 bracelets LAST YEAR!. that alone clearly proves he is way above any player playing in those tournaments.
And like elhh82 said, there is also deuce 2-7 draw, mixed games tournament which Ivey would crush.. No limit ones are ofcourse a way bigger field and way tougher. And there is also pot limit omaha tournaments which probably are also easier and a smaller field. (not sure what the 2-7 game is called, probably wrote it wrong)
And ofcourse variance is big in MTT, but it's Phil Ivey lol. If it was anyone else i'd laugh him in the face. But this is the guy who got 7 bracelets faster then anyone else.. If he runs equal to his EV he will do it easily imo, if he runs way below EV he might actualy still do it..
