Did Shane Mosley get tired after Round 3 or did Floyd adjust?

Floyd got a UD last night and won as expected in a very good performance, but there is something in question. Mosley, who is known for his endurance, looked very visibly tired only after 3 rounds? I'm not making any excuses, but it is what it is and it looked out of place, Shane Mosley not looking like his typical self or even the version that beat Margarito not too long ago. It seemed to me whatever Floyd did was not effective against Shane even when Floyd did come forward. This just clearly has me convinced a prime Mosley or Delahoya wouldn't of have let out Mayweather out alive from that ring. Mosley is not the best technical boxer and was landing his right hand almost at will. Then mysteriously he just ran out of gas. Great win for Floyd either ways he beat the man to become the man and if Shane was 100 yrs old and had beat the man to become the man guess what he's the man no excuses. So unless the Pac beats Floyd or Sergio Martinez I got him at p4p #2. Oh, and by the way, after what I saw last night, Floyd will have his hands full with Pacman.

 

Floyd fought a magnificent fight, but just like Steward was repeatedly saying Floyd could of stopped Mosley had he continued which was true, I think the same could of happened for Mosley knocking out Floyd in the 2nd round. That also seemed out of place for me how Mosley did not go after Floyd to finish him and Mosley has/had the reputation of being one of the best finishers in the game. Credit to Floyd, he took some hellacious shots, but credit has to be given to Mosley as well for almost stopping Floyd. Not bad for a 38yr old.

 

Good replies so far. It seemed to me when Shane realized his body wasn't doing what he asked it too and his stamina dropped by round 3, he started getting intimidated by Floyd's speed. He looked amazingly slow, stopped throwing the jab to the body like I had mentioned before the fight would be the key to beat Floyd, and also very out of place, he hardly threw his left hook, only to the body on occasion. I think for Mosley not being a jabber he did pretty good when he let his hands go. Everytime he jabbed to the body and then went upstairs he was having success and then he just stopped. Floyd even started coming forward which would of been Mosley's advantage, but the man looked gassed.
