To be fair I think striking wise the Rogers match was still pretty strong, it was the grappling which showed significant decline and ultimately thats what resulted in the following loses.
After those loses again I do think he looked a bit better, as much as thing he seemed more realistic as to what his current strengths were focusing mostly on standup and landing big shots. I do think at that stage he could potentially have still been competitive at the top level had he fought there.
Agreed, his striking was still top notch, although his training and mindset were not there for the Rogers fight. Actually, his training and mindset continued to get worse and worse right up to Henderson. When he started to get his training and mindset right with the Monson fight, he looked like a completely different fighter from his recent bouts.
Watch the 3 losses, and then the 3 wins afterwards to his first retirement. In the 3 losses, he bull rushes, throws recklessly, basically just going for the KO, and he does it being in his worst shape of his career. In the next 3, you first can tell 100% he's in better shape, that's a given, but watch how he fights too, he's methodical, complete opposite as before.
The difference between the Werdum and Monson fight is ridiculous. Werdum the more dangerous opponent on the ground, he dives right into his triangle choke. Monson, a good ground guy himself, but not of the caliber of Werdum, says no we're not doing that, and kicks the shit out of him upright instead. Why, because he was fighting and training smart again.
As far as his grappling goes, we will never know. He fought 3 tune up fighters in his wins that were never able to challenge him to use it, and it's a damn shame. He worked himself back to greatness if you ask me, and then decided to retire stupidly. Only to come back in 2015 washed up fighting bums, when 2015 should of been his true retirement after fighting the best fighters and probably winning during those years. It's sad to think about.
