Junior Dos Santos smashed Werdum and anybody he's faced thus far so I think he's a decent contender besides Velasquez. But other than that, I don't know.
I don't know whether or not you actually saw the Dos Santos vs. Werdum fight, but saying that he "smashed him" leads me to believe you didn't. It was extremely early in the fight and Werdum ducked into an uppercut, it's not like he got the shit kicked out of him for multiple rounds. Dos Santos is a decent HW, but should not be ranked top 10 compared to other guys in the division that just aren't in the "big" promotion.
Heavyweights that need to be signed to the UFC roster ASAP IMO are Overeem, Werdum, Sergei Kharitonov, Antonio Silva, Fedor & Aleks. The rest aren't worth a shit. If they add even half guys I listed, the UFC HW division would improve dramatically.

Aleks has some sort of blood problem and can't be cleared to fight in the states
Doubt it's a "blood problem," pretty sure that was a bad translation of something Fedor said that got out of control. The issue was more with the fact that he's a convicted felon and former Russian mob member, hard to get a work permit in the states that way. If the issue were an infectious disease, I doubt he'd have been cleared for all his recent fights outside the US.
Dana said Fedor is too expensive and a headache to negotiate with, plus he also lost which doesn't help.
How does that not help? Now M-1 realizes they need to be more lax on their end because Fedor will actually need the UFC now to maintain his GOAT status.
Kharitonov signed for Strikeforce which is cool, I love watching that guy fight, excellent power puncher with good ground game and throws, he was also the last guy to put a brutal whooping on a pre-bulked up Overeem.
I'm not sure why you even mentioned Mark Hunt because he got knocked the fuck out by a middleweight recently. (Manhoef)
The Manhoef fight was years ago (and I'm a big Manhoef fan, btw), and Hunt could still take the bottom half of the current "Top 10 Heavyweights" without much issue.
Barnett got popped for roids multiple times and is a proven cheater, also beating a shot Mighty Mo with 0 ground game isn't really a big ask and doesn't give you top 10 status.
But Brett Rogers gets Top 10 status from... a win over a string of nobodies, KO'ing AA and then getting the shit kicked out of him twice against real competition?
I'm also willing to bet Barnett loses to both Nelson and Dos Santos quite easily.
Delusional. Barnett is no joke, he just hasn't been put against any decent competition lately.
Roy Nelson is a good solid fighter, legit black belt and very underrated. He could have finished Arlovski until the stupid ref stood it up from FULL MOUNT.
Underrated? Lol. Nelson is overrated as fuck, name one person worth a damn he's beaten -- you can't, yet he'll be "number 1 contender" with a win over Dos Santos? What a joke.
