This week, Jen (@NHLHistorygirl) and Scotty (@scottywazz) talk about the evolution of the referee position. From getting knuckles broken in face-offs to donuts being offered to them, Jen will rundown the important history and changes made for the NHL referees. They'll also discuss the impact Willie O'Ree had and why he still isn't in the Hall of Fame. Plus, they'll talk briefly about the Hockey Days that happened this weekend in Canada and Minnesota.
