For Dan Craig, the National Hockey League's vice president of facilities operations, the most difficult part of the past 10 days was only tangentially related to the regulation-size NHL rink he and his crew have constructed in the middle of Heinz Field.
"The most challenging [aspect] is getting sleep," Craig said with a laugh.
Between rink construction, television production, attendance (60,000-plus) and even down to the play on the ice, every aspect of Saturday night's Stadium Series game between the Penguins and Philadelphia Flyers will be just a little bit different - and, in many aspects, more challenging - than your run-of-the-mill indoor NHL game.
