What rankings are you looking at? Flowrestling has Kaylor ranked #11 at 120, Cruz is ranked #13 at 138 and Phillips is #3 at 145. I would put Mason a little ahead of them both, but it's not night and day like you're trying to make it out to be.
Winning Super 32 gives Phillips the better folkstyle credentials but he has never made it to the Fargo finals as a Junior. Not that he couldn't do it but he hasn't.
I do believe Mason would be a 4 timer if he didn't get hurt. But as you put it, that doesn't mean that much when it comes to the national level.
