Mosley looked like an over-worked computer from beginning to end in the Mayweather fight. He didn't look like he was moving in real-time. It was quite weird to watch.
Fighters like Sergio and Manny to me are intense rather than jittery they seem more in control of what they doing. Berto and Alexander to me are jittery.
hopkins is a smooth fighter. so is chad dawson. froch also usually seems pretty cool. floyd is also smooth. cotto also seems to fight calmly. marquez seems a little jittery. pacquiao is just very active, but i don't think he's jittery
Canelo is suprisingly calm for someone as young as him.. Watching him against José CottoI was very very surprising at how relaxed he looked, even shortly after taking some big shots.
good mention. i agree 100%. he's going to be good. we will know his true worth after he suffers his first loss and how he responds.
