75th minute comebacks from 3-0?

Happens too often for it to be a coincidence that everyone seems to comeback from 3-0 in the last 15 minutes of the game.  It has happened to me where even I just feel sorry for my opponent because I literally did almost nothing and the AI moved without my assistance and put pressure on his offense even though I didnt change any tactics.  It was so disgusting I wrote him and said I was sorry even though it wasnt my fault it was the game developers for electronic arts.  But it is pretty obvious and not fair at all.  Thats coming from someone who has benefitted from it many times.
