Manny Pacquiao hasn't lost since early 2005, but that streak is going to be in serious doubt when he takes on Timothy Bradley, who hasn't lost—period.
Pac-Man, 33, is the clear favorite to walk away with the WBO Welterweight title, but there unquestionably is doubt surrounding him.
Plenty of factors lead to that doubt. Let's take a look at which ones stand out.
At first glance, Pacquiao is only five years older than Bradley and the age difference doesn't seem like a big deal. However, Pac-Man has 30 more fights under his belt and has a lot more wear and tear on his body than Desert Storm has.
Who will win?
This might not sound like the be-all, end-all deciding factor, but consider Pacquiao's strengths. He has incredible power behind his punches, but that's because his hand speed and explosiveness are second to none.
The first thing to go with age is speed and explosiveness. Should Pac-Man's speed suffer in just the slightest fashion, it will have devastating effects.
Pac-Man is finding himself in the news a lot, but fewer and fewer of those headlines are about his upcoming fight.
The question isn't whether all these distractions will hurt him inside the ring, but when they will hurt him.
It appeared the distractions were starting to take their toll on Pac-Man during his last fight with Juan Manuel Marquez, at least a little bit.
Will they continue to hurt his game inside the ring against Bradley? We'll find out soon enough.
Bradley is fired up
The undefeated Timothy Bradley has never had a fight of this magnitude, but he appears ready for it (via ESPN):
"He couldn't stop a 38-year-old [Juan Manuel] Marquez, so he's definitely not going to stop a 28-year-old like myself," Bradley said.
"They may think that Marquez just has Manny's number, but whatever Marquez can do, I can do 10 times better. He's great at counter-punching, and I'm devastating at counter-punching. My counter-punching ability is unbelievable. I beat most of my guys on counter-punching. It's effective aggressiveness with counter-punching."
Bradley's style may not be pretty, but he has the footspeed and big right hook capable of taking down the pound-for-pound champion.
Desert Storm is primed to do what Marquez came so close to doing, and most importantly, he has the confidence to come through on all of his smack talk.
Manny Pacquiao had better be careful.
