There was once a time when Reebok was a giant of the college apparel industry. That brand is now extinct, and another one is on its way to joining them.

Now in its fourth year, FootballScoop’s Who Wears What study is an exercise that tracks changes in the college apparel industry, changes that often seem microscopic on a year-to-year basis but, over the course of time, will monitor the shifting sands of the industry.

For instance, last year’s news highlighted the Under Armour’s passing of Adidas. Evidence of that? We wrote that Adidas was “stuck with” James Harden. Now? That arrangement seems quite different.

In 2017, we have seen the near complete removal of Russell Athletic from the landscape. The Bowling Green, Ky.,-based brand was already hanging on by a thread in FBS, and that thread has been cut down to a single piece of twine. Ohio jumped ship. Georgia Tech announced plans to do at its next available opportunity. Even hometown team Western Kentucky left the brand, soon leaving Southern Miss as Russell’s only brand ambassador in FBS. And with that, it figures the Golden Eagles will soon jump ship as well.

Elsewhere, Nike remains the king of the major college football landscape. Adidas and Under Armour have carved out their respective territories, but it remains Nike’s countryside. The Swoosh owns 67.7 percent of the Power 5 contracts, claims primacy in every Power 5 league —  18 of the 24 available schools in the SEC and Big 12 wear Nike — and outfits 14 of the last 15 national champions, including all 12 teams to ever reach the College Football Playoff.
