depends on what Faster equals in your brain.... are you talking about SPEED or QUICKNESS... those two are actually completely different things...
Usain Bolt is the speediest man on earth (from one end to another)... but not the quickest (acceleration)
Lebron James has best speed in the NBA.... but not the best quickness (acceleration, darting here and there like CP3, Rose, Iverson and so on)
If you go by speed... as in who can go from one end to the other the fastest... then its easily Lebron..... and we dont even have to give an opinion about this or show a video of him going fast as hell.... even tho there is enough of such evidence aswell:

because unlike Rose or anybody on this list, you can give actual PROOF that he is the fastest, in Lebrons book its clearly stated that he ran a 40 yard dash time which is almost as fast as Usain Bolt... 4.4 second (4.36) seconds:

"LeBron has a measured vertical leap of 44 inches and reportedly ran a 4.37 40-yard dash in the draft combine."
Usain Bolt 40 yard dash:

Compare 4.36 at 6'8"-250 lbs to the Fastest 40 yard dash times in human history:
http://en.wikipedia.org/wiki/40-yard_dash
Fastest time ever is 4.24 to 4.30........ think about that one for a second... and all those athletes in the list were between 5'5" and 6'2".....
Lebron is faster than Derrick Rose and faster than anybody in the NBA........ although i have to admit Derrick Rose is easily #2-#3 or so fastest in the NBA from coast to coast himself, he got great speed himself....
Lebron is faster.... more SPEED.... not quicker....
