I agree with you that there should not be expansion, but do you honestly believe that Saskatoon can support an NHL team? Saskatoon and Regina combined don't have .5 million people (I am taking the city stats). They could likely fill an NHL arena, but the corporate support wouldn't be enough.
Atlanta has a decent size population and look how that turned out. Some places just aren't hockey markets and the league has to realize that. You can't grow flowers in a field of s***.
