The Border Showdown is Back! 🏈 Before the SEC. Before the Big 12. Before hashtags and highlight reels — it was Mizzou vs. KU. A rivalry that goes back to 1891 and the return of the football rivalry since 2011.... This isn’t just a game. It’s 100+ years of noise, pride, and unfinished business. Whether you wear black & gold or crimson & blue — you know what this means. Shop these limited-edition tees online now! #bordershowdown #rockchalk #mizzou
