MLB commissioner Rob Manfred decided it would be a good idea to add time clocks to mound visits by catchers, coaches, whomever. It started a small argument among critics and analysts. Ultimately, however, timing mound visits didn’t change the flow of the game.
It made perfect sense to limit how much a team can elongate a game with no time limit if you really think about it.
As for the NHL, there is no doubting that regulation time is 60 minutes, with only a chance of a five-minute extra period. And if 65 minutes doesn’t do it, there is a shootout designed to end the game within just a handful of breakaways.
