They probably realized that calling the game differently when it comes to McDavid was leading to the Oilers being terrible and years of his prime being wasted.
I'm hoping they continue to call the game the same way regardless of which player is being harassed, but I'm not going to hold my breath. It looks dumb when McDavid draws 3 penalties a game but if they're penalties then they're penalties. The other team should stop interfering/holding/etc..
