== Copy Edit == 

 Working on the requested copy edit. Taking a break before I deal with the thick prose in the "History" section. One thing that stands out is that the "History" section here is actually more detailed than that in the main History of American football article. I would move some of this content over there, but it's already at FA status and I don't want to step on it. Thinning this section out will be tricky, as it is well-referenced. This will take some thought.
