Safety Suggestions:

Goaltender Masks:

Perhaps the installation of a mini-microphone just above the chin area of the mask.

Reason: To allow the goalie to warn the defenseman going back to touch the puck for an icing call. The goalie would be able to yell "Watch your back!" should he feel a forward was about to make him part of the boards. Thus, the defenseman would be able to brace himself for a check and possibly avoid a major injury.

Benefit: To say the least saving an injury. It would also keep the goalie in focus of what's going on in the game, taking away some of the stress concerning his ability to make the save.

Most times the goalies voice is not heard over the roar of the crowd, or the goalie finds it pointless to shout out anything. This way it becomes a responsibility of the goaltender to assist in plays of that nature and more. I have no doubt this will improve the goalies performance and game participation.
