The problems that I see for Randy are not Cardio or strength, but his speed, both headspeed and footspeed. In order to shoot in for a takedown, he has to get by a punch from sylvia. If you watch belfort/couture 1, lidell/couture 2&3, and couture/vanarsedale, you will notice that as he goes in for his takedowns he leaves his chin wide open for a shot. In the belfort matchup, he got his eye gouged and lost, in the liddell matchup, well we all know what happened there, in the vanarsedale matchup, he got hit a few times attempting this but vanarsedale didn't really do much damage.
I see the militech camp viewing these tapes and Tim training for a big power punch as Randy comes in, over and over again. Boom lights out. Unless Randy comes in with a radically different strategy than he has done in his last four or five matchups, it is going to be a very short fight.
I would love to see Randy win this, but in reality, I got to give it to the oaf, and believe me, I hate saying that.
