I believe the exact situation happened 2-3 years ago at the 2003 level with the Cyclones. Brought in some ringers, qualified for the E9, and then the ringers were never seen again.
IIRC, the league came down hard on the coach. I believe he was even banned. Maybe somebody closer to that situation has more details.
And when you all accept that this has nothing to do with fairness or player development, and EVERYTHING to do with the money being made by a select few people - this will all become very clear. But then, the D-Board won't be nearly as fun!
