Is she actually a good coach? I dont really know much about the team and what goes on in the comms. I can't really tell if EG doing this good is due to the players stepping up (Jawgemo) or the coaching (comps, strats, map picks).
it's the same for any coach or igl. we can only really judge with their performances, and eg is performing well, so we have to assume she's a good coach, but a lot of players have spoken highly of her so I'm confident she is
Once you see this game vs optic (low prep) vs the earlier game where eg beat optic (1 week for prep) you can really see how important potter's coaching and prep is to this team
