Well, Freaky Corey, agility allows you to adjust your speed quickly in play.

Agility - How fast your player can adjust their movement. If you want to dodge a tackle or head past a blocker you'll want high agility. Important for any player who needs to turn quickly...Lineman as well as speedsters. Agility also determines acceleration. You can have all the speed in the world, but without agility, you won't ever reach that top speed.
