This is a great way to look at it, especially if people consider it thoughtfully, and concede that if she was as bad as some claim at D, then MJ would never, ever let her line up there.
One question about her as an F ... we don't talk about it that much, but how is the defensive side of her game as an F? It isn't like playing all zones is a choice for the Badger forwards. Some say she doesn't skate hard enough to play D, but how do you play wing if you're not willing to go up and down the ice? I think her skating liability is overrated. Her top end speed is fine; if it isn't, that gets to be a bigger issue for an F at the next level. No matter where she plays, she'll like want to improve her quickness (stops and starts) in the coming years. If I compare her to UM's D as you asked, then Laitinen is probably the Gophers best defensive D, and Morrow was their best offensive D this year. The latter's game isn't that different from Edwards. Morrow's skills aren't quite at Edwards' level, but as all have pointed out, she's used to playing D. Would you pick Morrow over Edwards? I'd take Peschel over Edwards at D, but based on Saturday, but that's more about Peschel than Edwards.
