daemyn75,
I totally agree with the points you make.
But just 'cause you don't have a coach on ice with you doesn't mean you shouldn't do some goalie specific drills.
If you only play pick up, I guess it would be tough.
But if you have any on ice practice slots, you should take your butt off to the side and work some drills.

For instance, I tell my son that he can do the poke check drill against the wall by himself.
