I would question the wisdom of expanding or relocating the OHL into the United States. Attendance will always be good for the first year or too, until the novelty wears off. At that point, the hockey fans will continue to come to games, but the sports fans will begin to choose where they will spend their time and discretionary income.
In Michigan, football is king. It is High School football on Friday nights, so very few home hockey games on Friday nights in the fall are scheduled in Flint, Saginaw, and Erie. Home Sunday games are typically not played when they could compete with the NFL games that kickoff at 1:00. That leaves Saturday evenings in autumn, and I imagine the Saginaw and Flint front offices cross their fingers that neither Michigan or Michigan State are playing a night game. After Thanksgiving, then games can be any day.
But then you have to market an OHL game as being more entertaining than watching the NHL at home or at a local sports bar, where the beer is cheaper and doesn't require a ticket to get in.
And I will admit, I enjoy a good scrap on the ice. And based on the number of people that stand up when the gloves go down, I am not alone. But the rules have worked to reduce fights on the ice in the OHL, and I think that has hurt attendance in the states (when you don't have Connor McDavid). When I went to a few minor league hockey games in Saginaw before the Spirit came, I felt that the crowd was there mostly to see our goon versus their goon, especially when we played Flint. I base that on how loud the crowd got during a fight versus when we scored a goal. There is a gladiator coliseum mentality that drives U.S. Sports fans towards football and fights on the ice. Shameful? Probably. But it is what it is.
So that is the problem with expanding into the United States. Generally, we love football first. If football is not available, then we want to see some aggression on the ice, which is not part of the OHL anymore. If we want to watch professional hockey, we can stay home, hit a local bar, or even use our phone. There is small niche of people that have the time, the funds, and appreciate live junior hockey above other sport alternatives on a given night south of the border. So I would expect expansion/relocation would be more successful in Canadian town.
