Does the "best" mean percentage wise or the one he could get off at anytime? His highest percentage was easily the jump hook. But he could get off that fade-away anytime he wanted to.
How about the dunk especially those vicious put-back dunks or fast break dunks? For me it's Hakeem facing up, cross-over and pull-up jumper or drive right, spin to the baseline for the dunk or Dream Shake. Did it on Ewing, Robinson and Shaq with great success!
