What did the rules of the tounament say? Can a player be on only one roster? Doubt there is even tournament rules other then time and penalties served. Although unethical probably not illegal. They would not be the only teams that have done this.
Club lacrosse is un-policed because there aren't any universal tournament rules and even if tried to enforce them you would be considered a sour loser. Club lacrosse is about playing the highest level of competetion, blah blah.
