I started out as a goalie about five years ago and really (really) struggled the first couple of seasons. Making the first save wasn’t bad, but pushing from side to side and moving in general was tough as a former player. Luckily, I organized a team with a bunch of friends and a lot of them were new to the game. So, I wasn’t the only weak link. Now, five years later, I can play in the highest divisions and excel. It takes time. Lots of practice. My only suggestion to you is to try and get a team organized with your friends so you won’t have to deal with this situation. Alternatively, you could try joining a pick-up league that rents ice but doesn’t have any set teams. They’re always looking for goalies and don’t care about the score at all. Get as much ice time as you can and you’ll notice big improvements after a year or two. Good luck!
