The popular suggestions amongst the talking heads seem to be either:
a) Have the league mandate minimum quality standards for a backup goalie, and maybe dictate that he cannot practice with the home team.
and
b) Have teams carry a EBUG all year, who would presumably practice with the team when needed, and serve some sort of support staff role the rest of the time.
There are substantial hurdles with both approaches.
On A.... You cannot pull from professional leagues, as these guys are under contract to another organization. If they get hurt, that's a big problem for them and the other organization.
Ideally, you want a guy who does currently play competitively, which leaves university goalies.In the Canadian cities, it is probably practical, as each Canadian team can schedule one of the 3 goalies on a university roster to be at the game.
In the US however, this is much more complicated, as NCAA rules would likely prohibit university goalies from doing this.
Furthermore, if he doesn't practice with the NHL team, how is he supposed to stay in shape? At least if he practices with the team, if he plays for the home team, he's familiar with NHL shot quality, and they know him a bit. If he plays for the road team, at least he knows what he's facing.
On B.... This does on the surface seem like a reasonable approach. Get a guy to be the "assistant goalie coach", or equipment guy, and have a traveling 3rd goalie with you at all times. The problem with this is -- you're still going to get a player who potentially hasn't played competitive hockey in years. Seems to me that if the league mandated that teams make this position, David Ayres might still be the Leafs EBUG.
