If you can do that then great, there is no such things as a "not supposed to happen", its up to the player to decide how they spend that first minute or so.
No one seems to play with defenders off any more but I did have a few games with them off many patches back and it makes for a very different game. Much faster, and you can harass earlier etc. It's a fun way to change things up. Slightly off topic, but you reminded me with the fast expansion.
