Kevin Warren had one job when he was hired: secure the bag.
And he did. Under his tenure, the Big Ten landed a seven billion-with-a-capital-B television contract, securing the conference's status as Old Uncle Pennybags for the foreseeable future. Add in a few legendary west coast programs (barring something crazy), and all of a sudden the Big Ten is a truly national brand with a presence in the three largest media markets in the country.
There was a bunch of other not as fun stuff that happened over the last three years that we're actively trying to shove into a dingy locker in the bottom of our subconscious, but now that's he's shuffled off to the greener pastures of the, uh, Chicago Bears, history will probably look back at the Kevin Warren tenure in a mostly positive light.
