Sam Vimes :
The game was coded by people who think football and soccer are the same thing, so the stats are in soccer language.
In American football, the game's "GA" would be closer to "points allowed".
Likewise, where this game uses "MP" (matches played) the real life equivalent would be GP (games played), and the "counter-attack" notification during play would be either "forced fumble" or "interception" depending on circumstance.
To be fair most people in the world would consider football and soccer the same thing!
