The goal MSU scored was 80% on Shepherd. She misplayed a ball, ran past the defender, left a massive gap behind her and then when she got back made a stupid, unnecessary foul.
The only argument I would make to your point is that I think Shepherd has been inconsistent the whole year. She has had some great games and some terrible moments as well. Regardless, the 6 is the gap between the midfield and defensive line and that is where the space has been.
