If Floyd lies on the ropes and just lets Guerrero punch himself out, the fight could appear closer than it actually is. This is what he did against Cotto, and he actually got touched more than we're used to seeing him touched. At the same time, it's hard to land SOLID shots against Mayweather. He'll give you some body (picking off a lot of it with his elbows), and pick off pretty much anything that comes upstairs. Floyd gives up some early rounds simply because he doesn't throw a volume of punches, but as his opponent either tires, or exposes holes, he steps up the attack as the rounds go by. Guerrero presents and interesting challenge, but I expect Money to win by unanimous decision. If you look back at how he fought Oscar, he followed that plan - lay on the ropes and let Oscar bang away early, then start tagging him when his arms got a tired.
