I've heard from several sources that DoPS is a little rattled by the appeals to its rulings. Bettman backed George Parros in all three (although
David Perron still can get money back from the independent arbitrator).
Rasmus Andersson and
Charlie McAvoy appealed punishments of fewer than six games, meaning Bettman was the final authority.�
That never used to happen, because everyone felt it a waste of time. What it did, however, was remind Parros and company to make sure everything had strict precedent. All rulings need to be defensible by previous punishment, because challenges are coming more often.
