He doesn't have a quick enough dribble to do that with the best of the PG's. For the most part, James is a straight-line dribbler who only attacks when he sees a path to the basket that is directly in front of him. There is no doubt that James has great court-vision to find the open jump-shooter cross-court when that help comes. To me, that isn't typical of a PG.
he has a damn good enough handle for it...if you're using more strength to maneuver what really counts is control more than quickness
plus whether or not muscle mass slows you down depends on where you have the muscle mass
and muscle weighs more than fat..but unlike fat the muscle works...
in other words when you're on the run...the fat slows you down because its just dead weight...muscle has weight but its not dead weight
now i'm not a trainer or anything...but thats basically it isnt it?
i dont think increasing muscle mass has slowed lebron james down at all..
hell he has been 250+ since being in the league...
