Muhl is a great talent, although the club situation makes it hard to tell how great exactly because it's pretty rare for a player her age to be given the responsibility to make everything happen for her team. Her current commitment to the college process means that she will probably stay there for now whereas if she was on the definite professional track, she probably would have signed a contract with a team in a different country by now and be more heavily focused on long-term development.
