A square ball out to the wing back from the centre circle is a high % pass. It will go to the player 99.999% of the time. A forward ball between two CBs into the path of a strker is a low % pass, it migh go to the player 30% of the time. Buendia plays a lot of the latter. Nakamba, for example, plays a lot of the former. You can't compare their stats and say Nakamba is a better passer. Actually watching the game proved that's not the case.
