According to this article, Cull applied for the Aeros job and took the first one that came along when the Sudbury Wolves (OHL) came calling.
As far as an update is concerned regarding the head coach, I think we will all know something when the playoffs end. There are a good number of names out there and competition, I assume, is quite fierce for this position. I don't think that Todd Richards is going to get the kind of honeymoon that Mr. Lemaire got in St. Paul. The next coach of the Aeros, I expect, will be the next coach of the Wild.
That is my take ... who would you like to see coaching the Aeros next season?
