This is a post I have been meaning to write for about a week or two, and UCLA's recent renewal of its deal with Adidas was the final straw. Below is a list from the Big-6 conferences of those teams that are currently in partnership with Adidas as its main sporting supplier.
As you can tell, some conferences have very weak representation with Adidas (ACC & Pac-10) while others such as the Big 10, 12, and Big East have a fairly strong representation. It seems like Adidas does well in the Northeast and Midwest regions of the country, as well as a pretty good job in the South and Plains. Clearly though, it needs to ensure it uses its lone school in the West properly, because losing it somewhere down the line would be devastating to it. Lets hope the people at Adidas realize that.
