They already have commercials built into the games for minor stoppages, and they want the actual commercial break to be even longer? Was that not enough?
Long reviews, more and more commercials, refs continuing to not drop the puck at faceoffs, they're slowing the game down more and more.
Combined with hitting being taken away and a purposeful decrease in fights allowed, the league really wants to kill themselves and decrease interest.
If I wanted a slow and boring sport devoid of physicality, I'd watch the NBA.
