I found an old article in the Gazette about Werner’s transfer from CC to Michigan and while it didn’t definitively say his reasons why he decided to leave, it mentioned how after getting off to a very hot start his freshman season, he hit a point dry spell going 3 months without a goal until, naturally, against UND. Article went on to say he fell to the fourth line starting the second half of the season, so perhaps there was some consternation there and his role with the team. I also read that he moved from Texas to Michigan when he was 12 to fully invest in his hockey career.
