AJ,
I spent over two years in Portage trying to do exactly this and here's some of the roadblocks that we ran into.
Most middle schools athletics are run by the assistant principal. It would take a lot to get a school to change when the season is. A lot of The Region has their middle school season from late Oct. through Dec. It would involve a lot of gym space usage changes. We had a pretty supportive principal at Portage for a while and he just couldn't do it because all the other activities are set. Moving wrestling season would have interfered with the floor hockey league they had in the spring (I know...floor hockey. Let's all roll our eyes at the same time). Once a principal has a year set, it's not that hard to do the same schedule for the next year. Changing a season would involve a lot of schools (everyone on their schedule) to do the same.
There is a ton of middle school coaching turnover. Not many stay at this level for a long time and a good percentage that do, don't want to change.
I love the idea of getting everyone in the state on the same page. I think we'd need a middle school organization that the schools would recognize. That is a tough job because of the extra work it would take for a principal. I think for that to happen, we'd need a MS baskball association to join the fight with us.
