I think most people are going to agree with this one , it seems pretty obvious . Although we all (well , most of us) thought that Nogueira's terrible performance against Mir was because of a "blown knee" and a staph infection(that was the common sense at the time backed by Rogan , Dana and most of the fans) , it's very clear that it was not the case . The Velasquez fight was like a fast forward of the Mir fight - Nog just looked old and pretty much helpless. He had absolutely no answer for the kicks , and he got tagged a lot with punches before the final punch landed. His famous ability to absorb punishment was non-existant . He didn't even attempt a take down and even if he did , being so slow there's no reason to think he can take down Velasquez or even Mir.
I think this just shows us that if anything , the Couture fight was the exception to the rule - and the rule is that Nog is not an elite heavyweight anymore. This just shows that Couture too , is WAY past his prime. I don't think that the Randy that beat Gonzaga a couple of years ago would have lost so decisively to this slow version of Nogueira.
Not to take anything away from Cain , this was still a great victory and I think he pretty much earned a title shot , either him or JDS.
So bottom line - I don't want to see a Nog-Mir rematch , and I think Nog should consider wrapping it up. He's been in the business for ages , went to the top , and it's all downhill from here...
One last thing - I hope this doesn't anger Nog fans too much but Nog keeps attributing his losses to injuries . He did that after his fights with Fedor and Barnett (I don't have time to look those quotes up again ). I'm not saying Noguira lied about the injuries he had before the Mir fight , but I'm saying that sometimes it's easier to blame injuries than the fact you're over the hill . No one wants to believe they're over the hill - not the fighter himself , not his camp and trainers and not the fans.
