There were issues with officiating in Game 1 (more so linesmen than refs). I don't like the idea of adding referees to the game. What if adding three doesn't work? Do we add a fourth? The two on the ice need to do their jobs better. It's that simple. If they can't do it, hire someone who can.
EVERY seat on the glass should be NHL referees. They have electronic voting mechanisms (like the old episodes of Americas Funniest Home Videos) and every play is reviewed and voted on by this plethora of officials.
Also fans can call in penalties when they're watching on TV, similar to the PGA.
