Handling, ball management and capability to keep the ball vs a tackle, it could be like dribbling but this last one is called like that when the player runs..
So let's say, Handling avoid counters.
Creativity = affect to the chances of, using the other abilities that the player have. Not sure if, with abilities it means the other skills ( so is like a balance that increases the ratio) or, maybe for example, if a player have the ability to assist by default, then the more creativity = the more chances this particular action will happen during a match.
I guess is more related with the 2nd point... with particular game actions.
Still this depend too, of the "internal game roles" so, at some point we could do a classification of players, (key players, not contributive, etc) and see if, increase the creativity in the key players really makes them more "perceptible" during the match.
