There are a lot of important roles, not just those on the ice.
Once your kid is playing organized hockey on some type of select team, the manager role is huge. All you need to be a good manager is a level head, good organization and communication skills, and the ability to role with the punches. I coached youth hockey allstar level, and the choice of team manager was huge - the difference between a good or bad season was largely on the quality of team manager you found for that role.
So to the OP - if you're motivated and want to help, don't be discouraged if you lack on ice skills, a hockey team is more than that - there are other ways you can be a key part of the teams' success while you work to develop your on ice skills.
