I think that a player like Fiser is probably on 100% so she might be back. The other seniors I don't know. Kemmetmueller is a nursing student so I am sure she wants to get out in the real world. I bet Partain gets a lot of money too. She might be back.
If a player is not a star on the team, either for the financial reasons already mentioned, or out of self-realization of the need to make way, or of coaches giving gentle nudges to make way, almost all players I have to believe will move on and start their lives. Fiser and Partain may stick around one more year maybe. Or maybe life/family choices outside of softball will take them away.
All together what a fantastic group of players for the Univeristy this group of seniors were... and ambassadors of the sport to Minnesotans.
