UFC on FOX: Is Junior dos Santos the Best Heavyweight of All Time?

Junior dos Santos is unstoppable.

He has won all eight of his UFC fights, finished six of those fights, completely dominated the two opponents who made it to a decision and now he is the new UFC heavyweight champion, after knocking out Cain Velasquez at UFC on Fox 1.

Other big names on dos Santos' resume include Fabricio Werdum, Gabriel Gonzaga, Gilbert Yvel, Roy Nelson, Mirko Cro Cop and Shane Carwin.

That's an impressive hit list, no doubt about it, and there can be no denying that dos Santos is the best heavyweight in the world today.

But let's take that one step further: Is Junior dos Santos the best heavyweight of all time?

No, not yet.

Everything that dos Santos has accomplished so far is incredible, and he definitely seems to have the potential to be the best there's ever been in the heavyweight division, but he's not quite there yet.

When you look at guys like Antonio Rodrigo Nogueira, Randy Couture and Fedor Emelianenko, it quickly becomes clear that dos Santos has not yet established a legacy worthy of being called "the best ever."

Dos Santos took a big step towards being the best ever last night when he destroyed Velasquez, whom many believed was himself going to be a contender for the best-ever heavyweight.

I think dos Santos could eventually be the best-ever heavyweight, but if he retired after tonight, he would not be remembered as the best there ever was.

Luckily for dos Santos, if he does want to be known as the greatest, now is the time to establish that reputation.

The UFC's heavyweight division is arguably the best it's ever been right now, and then there are Strikeforce fighters you can expect to see in the UFC at some point—Josh Barnett, Antonio Silva and Daniel Cormier.

JDS has a tougher field of challengers ahead of him than possibly any other UFC heavyweight champion, and more wins over top guys could earn him the title of "best heavyweight of all time."
