This was a good post...not really a whole lot to disagree with. I was always a fan of Mirko anyhow...practically screamed at the tv for him to throw a damn leg kick against mir. He had his moments against jds too.
Honestly by those last three UFC matches before he was cut I don't think Mirko's heart was in it at all anymore but generally by the time of his second UFC run I think physical decline had ment he had to shift his style.
Mirko at his best really depended on rapid movement and landing devastating counters but as he slowed down he simply couldn't fight that way anymore and had to depend instead on slowly stalking opponents down and looking to wear them down with boxing.
Again for me Gonzaga was a combination of him not adapting well and simply facing a dangerous opponent who gave a great one off performance, similar to Randleman.
As far as Stipe goes my feeling is that in todays sport he benefits from being a solid all rounder, his sub game perhaps hasn't been tested much but he's a pretty good wrestler, a good boxer and has a decent chin. You look at his recent wins and...
Hunt - Obviously had a weakness in terms of cardio and as always takedown defence isn't ever fully dependable against decent wrestling.
Arlovski - Chin questionable and obviously not as fast as he once was.
Werdum - Boxing defence and offensive wrestling both very questionable.
In the Pride era I don't think he would have as many fights where opponents are giving him clear weaknesses to target, Fedor, Crocop, Nog, Sergei, Aleks, Barnett, etc would I think all clearly be tough matches for him.
In that respect I actually think JDS would potentially do better, he does have weaknesses and I think he'd take a a lot of punishment against the striking talent of that era but equally I think his mega chin and his handspeed/power brings something a bit more unique to the table.
