The line rushes and skills and systems work that the teams do as a whole are pretty much not applicable to replicating game situations for goalies, so most coaches just kind of leave them off to do their own thing, but also have high expectations for them.
I think this is changing quickly.
When I played net 25 years ago, there was next to no coaching during practices for us goalies. We basically had to search out the local goalie coach and pay for tutoring out of our own pocket.
5-10 years after I left, I saw an increase in demand for coaches that knew how to work with goalies. This was coming more now from teams as opposed to parents. Today, on rep teams, a goalie coach is almost expected. We also put aside hundreds of dollars from our budget that goes towards our goalie training as well. Entire organizations also work out plans with local training facilities to once again work on the goalies.
In a typical practice I run for my daughter's competitive team, I allow 30 minutes for our goalie coach to work specifically with the goalies. The coach then stays on the ice for the remaining hour to continue to help out with only the goalies.
Coaches certainly do expect results from their goalies. Finally most of them have realized that proper coaching is what is needed.
