By Chris Williams: The nearly 40-year-old Shane Mosley may have lost the fight to Manny Pacquiao last weekend, but he sure did a good job of exposing some painfully obvious flaws in Pacquiao’s game. Mosley, who isn’t really considered a great boxer, was able to fight defensively, making Pacquiao miss all night long and picking him off with a harmless jab. Mosley showed again and again how easy it is to hit Pacquiao with a jab and make him miss with his shots.

If Floyd Mayweather Jr. has seen the Pacquiao vs. Mosely fight, he will have no doubt discovered how hittable Pacquiao is and how poor he is at cutting off the ring. Pacquiao looked to be about the same age as Mosley in the fight, as neither of them looked quick on their feet. They basically looked like a couple of aging fighters plodding around the ring. Pacquiao is really slowing down.

The difference between Pacquiao in his last two fights compared to how he looked back in 2008 when he beat Oscar De La Hoya is shocking. The foot movement is gone and Pacquiao looks so much slower, even though he was only a few pounds heavier in the Mosley fight compared to the De La Hoya bout.

Pacquiao couldn’t catch up to Mosley for the most part, and that wasn’t because Mosley was quick on his feet. It was because Pacquiao is slowing down. He reminds me of great baseball player that can no longer cover a lot of territory in center field. Pacquiao couldn’t cut off the ring against Mosley because of his loss of movement. As such, Mosley was able to glide around, spearing Pacquiao with jabs at will. It was interesting to see Pacquiao blame it all on Mosley after the fight, making it seem as if Mosley was the one responsible for the fight being so dull because he wasn’t trying to make a fight of it. Sorry, but that’s not the reason why the fight was entirely dull. It was Pacquiao’s lack of lateral movement, his inability to cut off the ring and his slow plodding that made it possible for Mosley to move him around him with ease. Mosley exposed Pacquiao’s slowing footwork and it’s scary to think of what Mayweather would have done to Pacquiao had he been in there with him.

I think Pacquiao’s career can be prolonged another two or three years if they keep matching him against slower fighters and ones that are old and past their best. Pacquiao can keep winning against the right type of opponent. He’s planning on fighting 38-year-old Juan Manuel Marquez next after having faced Mosley, Antonio Margarito and Joshua Clottey in his last three fights. Marquez fits in nicely with that bunch. He should be slow enough for Pacquiao to win.
