For my money, Rizzo should have probably been fighting in the UFC for the past few years(the Yvel loss really set him back) as a top level gatekeeper, giving everybody trouble and when he's on, I believe he's a scary challenger for anybody, even at his age.
Monson & Rizzo are the two best HWs for Fedor outside of Zuffa(I suppose Cole Konrad could also be in the running) and this should be a really great indicator for Fedor going forward(I still think he'll do another fight, maybe for Showtime....)
I have Fedor as a heavy favourite, but I wouldn't sleep on Rizzo and think alot of ranked guys won't want to fight him.
