Tyler Migura was the captain of Harvard when they came to UND last a couple years ago. I think he played his sophmore year at south and then left to somewhere in the ushl. Paul Weisgarber captained air force for a couple years as mentioned above, including for their visit to the Ralph last year.
Danny Wurden played a season at UW-Stevens Point. Erik Galt was standout player for Concordia. Sean Deichart was on St. Thomas.
From North, McLean, i can't remember his first name, played somewhere out east that I forget. Most South grads that could maybe have made it ended up playing golf istead (i think askew).
