Teams should always look at talented improvements. They do need a goalie.
Why would they need a goalie? Looks like she's doing a pretty good job.
Is that a serious question? Because every team at this level should carry two just in case of injury, illness etc. regardless if “she’s doing a pretty good job.” Every high level club will do this if they’re smart and want to preserve a competitive team. If a goalie can’t handle that they need to check their ego at the door.
