So how come Pac was able to get Better while Floyd declined?

I was thinking about this and watching some tapes: Floyd's speed and flexibility (away from his punch-out-put) has seemingly declined on some level as he settled in at 147...while Pac has continually improved in many ways and has at least kept his speed unless some think it is better...don't know. So how come Pac was able to do it but not Floyd? Training, Nutrition...with Ariza and Roach's help? Of course. But why not Floyd? Well, maybe it was because unlike Pac who needed to get better because he did well but not "great" in the lower weight divisions knew that if he continued to fight on and move up he had to continually get better. So, he looked to advance himself with the help of Nutrition, Training set up by Ariza and Roach to help him become better technically. Hard Work and Study to improve. Floyd: well, after moving up to 147 and settling in, I guess it can be looked at as if he sat on his ass and when you do that, you decline. There is no need to improve and it is when you just try to maintain your ability you can actually start to slip with age. The way to beat age is to find new ways to stimulate your mind and body. Pac did it; Floyd may not have. Now if Floyd was forced to fight the best at 147 maybe that would have kicked his ass in gear to continually improve. Kind of like War. Those who settle in and get comfortable and don't have a major threat on the boarders, tend to become vulnerable and fade away while others who are constantly in warfare and have a fear level to survive, strive to continually improve to live. You have Sr. throwing out PEDs use against Pac...but maybe Sr. and little Floyd are "Old School" on their approach to athletics/boxing. Hopkins was like this throughout his MW career and he slowed down when he hit his 30's so he had to start pacing himself and picking and choosing when to fight during each round. He moves up to LH and he comes into the "Now" and hires a Pro...Mackie Shilstone...someone who is known to train some of the best athletes in the World to improve in the modern way. Hopkins became refreshed. Still declined compared to his early days but seemingly better than he was at MW. So who does Floyd have? Big Leonard? I don't know. I'm a bit ignorant on this subject with him. But one thing is for sure: he seemingly is not the same as he used to be and Pac has been able to continually increase weight and get better...as well as his willingness to add on to his arsenal. Now it wasn't a huge leap in technical ability as some may think it is...No...and it did take a long time to improve even slightly technically for Pac....but at least he put the effort in to get the desired results.
