Should Floyd hire Alex Ariza ?

Floyd has always been able to get by doing things his own way whether it be his training and conditioning or his not really listening to his trainers in the corner, etc, but now that he is older, should he get a fitness and nutritionist like Alex Ariza in his camp ? I think he better do something different or that "O" will definitely go over his next 3-4 fight if he keeps fighting younger and bigger opponents. Floyd should have phucked Chino up the other night with quick hands on the inside and or danced and boxed him then broke him down with speed and combinations but he didn't and I'm not buying the story about him giving the fans a fight they wanted to see. I had Mayweather by an 8-4 difference because he was the better and cleaner fighter with much crisper shots, but from the walk to the ring until the end, something seemed off. A change is in order and I think shaking up his camp a bit with a guy like Ariza might be the perfect antidote. Thoughts ?
