Lol who cares who if Cain didn't defend the belt against the greatest fighters? Cain and JDS actually had to fight monsters to get to the belt (unlike Brock, Couture and Carwin). Cain beat Rothwell and Rothwell has been beating the fuck out of guys who would get a title shot with a 2-3 win streak. He beat Nog when Nog was looking fresh after dominating Couture and Kongo when Kongo was on a 3 win streak and was on his way to title shot.
Who else is Cain supposed to fight besides Werdum? All the guys with hype keep getting derailed: Stipe, Reem, Browne, Hunt, etc. Bigfoot, JDS and Doom keep weeding out the weak and Cain keeps beating JDS and Bigfoot. Its pretty much Cain against Brazil and there's only one Brazilian left.
So who is Cain supposed to beat to not be over rated when he's clearly above everyone except maybe 2 guys (and he already beat one of those two)?
JDS is another one who wouldn't have to defend his belt against many "elite" fighters to be considered one of the dominant champs / GOATs since he already beat his competition without the belt.
I just don't see how champions can be considered "hype trains" or "over rated" around here except for maybe Serra and Brock who didn't earn their title shot and guys like Chuck, Couture, Arlovski, Mir and Sylvia who were big fish in small ponds.
But any post SF-UFC merger champion @ HW can't be over rated and any post UFC-Pride LHW / MW champion can't be over rated. Fucking dumbass fans.
All that's left for Cain is Doom and that's it. Unless someone beats Doom (if Doom loses to Cain) or JDS, they shouldn't get near a title shot and the fact that Cain beat these two just adds to his dominance. Similar to Fedor, Nog, CroCop trinity.
