As much as I want Wallner out of the lineup, I also want to make sure that the players in St. Paul are ready for the show before calling them up. Temporarily, it would better just to bench Wallner for Martin prior to calling up and Erod. I do think calling up Erod, Jenkins, or whoever is ready is best for the long term. If you reach a position where you think you can give Erod full playing time, then swapping him for Wallner makes sense.
