Let's take another look at this thing.
The 3-on-3 overtimes are getting all the press, but the NHL's "other" new rule could see some changes already this season. And it's pretty much all Jack Capuano's fault.
The Coach's Challenge was put in place so that teams could ante up their lone timeout in the hopes of getting a goal overturned in cases of potentially uncalled offsides plays or goalie interference. But there's concern that some coaches are throwing the challenge flags as a sort of speed bump that gives their team a breather immediately after a critical goal and throws the other team off its game.
