Yeah, actually after having had time to think about this, to me it's a sad day. UFC HW division is really thin. Granted, anything can happen (remember the lucky shot by Randleman) but the only one who MAY (and this is really a stretch) present a challenge will be Sylvia and that's only cause he's big and has a damn good chin. Glass jaw Arlovski? Decent striker but with his chin, if Mirko connects I fear for his life. Vera? Decent striker, untested but will definitely be overpowered by Mirko. Vera should drop to LHW as he'll match well with Chuck and Rampage. Kongo? Too freakin' slow. Herring? Already been KO'd by Mirko and he hasn't shown any improvements since then.
Sigh, can't do much about it anymore but I really wanted to see Mirko/Fedor II, Mirko/Hunt II, Mirko/Nog II, Mirko/Werdum. Those are competitive matchups. Heck, even Nastula and Kharitonov would give him a more competitive match than what UFC has to offer.
