- Midway through the season, the league implemented the "David Leggio Rule:" in the event the goaltender deliberately knocks the goalposts off its moorings to prevent a score, the score is awarded anyway. The rule is named after Leggio, a goaltender for Red Bull München who is infamous for the tactic.
