When I just started covering the Komets in 1990, I asked Al Sims for a tip on how to learn the game. "Watch a player for an entire shift without watching the puck." You could easily tell who was playing hard and who wasn't. Watch who is skating straight up instead of knees bent and in position. Who is skating hard on and off line changes? Who is only skating hard when they have the puck?
Let me know what you see.
