Maybe the name of it sounds like we should give it to only fast players but it's not that. This card should be given to agile players who is able to do very quick body turns in real as the card's explanation suggests. I think that it's important because it's sth like the dribbling styles (type 1,2,3,4) in the game that represent a player's way of dribbling for the realism of the game. For a start:
the players who are given this card in default database;
wright-phillips (haven't any idea)
alexis sanchez (true)
villa (haven't any idea)
diego capel (haven't any idea)
donovan (haven't any idea)
m. moralez (hai)
s. blanco (hai)
in addition to them;
are the players who's come to my mind as candidates for the card first.
these are my thoughts. so let's see your opinions, please. it'd be great to get everybody's contribution for this important work.
