Coach Tortorella is known for his old-school mentality about the game and his quick fuse with the media. Over the last few years, the NHL has incorporated more technology behind the benches to help players watch replays of their shifts and to aid coaches in the replay challenge aspect of the game.
While the technology can definelty help the players, Tortorella makes a great argument. Hockey is one of the few sports where the next shift can impact the entire game, so keeping the players mindset on the next shift and not in the past can be extremely beneficial. There is one player though who apparently loved the iPads.
