It's not often you see a head coach lose his cool during a game in today's NHL, but Sheldon Keefe just lost it yesterday. Before I say anything more, here is the footage in question. <div align='center'><blockquote class='twitter-tweet' data-lang='en'><a href='https://twitter.com/TicTacTOmar/status/1607935675462201344?s=20&t=5-DwIiRELC_MRpuzkLMHRA'> </a></blockquote></div> <div align='center'><blockquote class='twitter-tweet' data-lang='en'><a href='https://twitter.com/TicTacTOmar/status/1607942114498826241?s=20&t=U8fN6uoWrfzC9T6AV6N8lw'> </a></blockquote></div> Obviously, it's always good to see a little emotion behind the bench. On the other hand, there's a limit to everything and all indications are that Keefe has crossed it here. I wouldn't be surprised if the National League reacted to the Leafs' head coach's actions with a possible sanction.
