NHL? Aw hell no...... It might be the hardest sport to play, but definately not to coach. Probably one of the easiest to coach truthfully....I dont think it comes close to the duties that an NFL coach carries......Terminology, playbook, gameplanning, all the assistant coaches, salary cap, 40+ team roster and the list goes on......
For the NHL, yeah, they create lines and matchups and shit, but for real, I could probably do that......The outcome of hockey games has more to do with what the players do on the ice than what the coaches do.....Its not like they can call tiemouts every 5 minutes and call plays cause in hockey u only get 1 timeout per game.......You never hear a commentator say after an NHL win, "Wow Bob, that coach really made some good calls out there today"
