Warren has pretty broad experience in sports, law, and running operations within a sports team. It seems he was very highly thought of and a candidate to be the next NFL commissioner (

You would think a lot of the organizational aspects of working in the front office of an NFL team would transfer over to running a college conference. Maybe the Big Ten was enamored with having someone from the NFL working for them that could help raise the conference's profile? We don't really know and never will. Like I said, I've seen in my career a few head scratching hires in my profession and heard about others from my peers. Sometimes those hires work out, sometimes they don't. I think during the pandemic there are very few leaders that are looking like they have the right answers, because at this point I don't think anyone knows the right answers.
