I'd assume he's getting poached to the RTC, unfortunately cornell seems to be having problems retaining the big names.
Incidentally, yianni could very much benefit from the OSU traditional style, though that seems destined to change. He's said himself that he's not that physical, uses lots of elbows (though they don't seem to work like they used to for anyone), and his motion is kind of plodding and russian, but it seems to make him vulnerable. The whole OSU mongoose stance would probably help his head and hands defense and only sacrifice the physicality that he doesn't really have anyway...additionally he has seemingly every misdirection in the book, so that feeds into the style as well.
Normally I'd scoff at someone suggesting such a dramatic change to such an experienced wrestler, but he seems like he's hit a wall, and the great ones can make changes late.
