I'd have to disagree with you too SP. Notice that Floyd brings his right hand up to block everytime Roger throws a left at his head. The same is when he slips and uses his shoulder, etc. It's all responses, and Floyd and his uncle play off each other so well that it seems like just another parlor trick.

Though I agree that a lot of trainers will use the pads just to make their fighter's look good, when Roger and Floyd play off of each other with the pads, it transitions very well into FLoyd's fights. All those moves and reactions are being reinforced during the pad work. Now on the flipside in regards to those other fighters that are made to look good on the pads, that pad work doesn't carry into their fights.

Now if you look closely you can see a lot of subtle things that Floyd does. Those precise little shifts in his footwork, exit strategies, and flowing from one movement to another is brought out in that training. I'm not saying this to be patronizing, I'm saying that there's a lot more to it than what it looks like on the surface. Roger is a big contributing factor with Floyd's performance, because it's the man with the pads that determines the situation that is to be practiced.
