Actually....in order to have the ability to throw that many combinations from all diffrent angles while MOSTLY without planted feet shows A LOT of coordination. Balance as well. You are mistaking Manny's unorthdox and "shifty" style where he's bouncing in and out, left to right ect as not being coordinated. It doesn't look "smooth"...b/c it's not. The only thing that is smooth about Manny are his combination punches that are extremly fluid.
If you see Manny as a 1-2 kind of guy then you need to stop watching OLD fight footage of Manny. He USE to be that kind of fighter with the 1-2 thing that even then was effective...but his evolution is NIGHT AND DAY. Try watching some of his more recent fights post 2003!:good
