I watched most of the game and thought the officials did a pretty good job with everything that I saw. Obviously no real audio but tough game to work.

Nightmare scenario
 

at midway through second period there are FOUR people ON the floor. The HC, what may be an assistant, standing with one foot on the floor.. and two standing spectators at the end of the bench standing with their toes over the line. It was an awful situation. When the start third period they had cleared those hanger-onners near the bench. Game management failed miserably through first half.
