The advantage of this cheat is simple: It takes out a few of the computerized defenders, and it throws the defense player off by not allowing the defense player to see where your receivers are going. In other words, all you see on both player's lynx's is a pretty much blank screen with nothing but a quarterback and a few rushers....With enough practice, one can have little trouble blindly throwing passes like this.

Lastly, don't try this cheat on the "Real" arcade version of this game. It doesn't work. Actually it's quite amusing what happens. When you think the quarterback is going to throw a 70 + yard pass, he/she/it ends up throwing a pass that lands like 1 yard right in front of the QB. Try it if you're ahead sometime on the arcade version. Is kinda amusing...
