Linear,
Just adding to the athletic ability discussion.
When I talk about hand/eye coordination - I take that to mean the direction and quickness at which your hand/arms/shoulders anticipate and react to what you see.
In just about any sport I can think of - if this "coordination" isnt sharp - you probably will not last long - and in certain sports - you will most likely be carried off the field on a stretcher - regardless of how fast or strong you are.
