Keenan Cornelius and Josh Hinger train together at Atos Jiu-Jitsu in San Diego. Both are black belts under Andre Galvao.
They're not closing out divisions like many teammates do but instead are facing off against each other in the finals of the absolute divisions.
From what we've heard, there's no bad blood between the two -- they just want the mat time. Competitions are as much a learning experience as time spent in the gym, and Hinger even wrote about the benefits of friendly rivalries in a recent article.
One of the best things about jiu-jitsu is you can go all out in a match only to shake your opponent's hand after, enjoy a chat, and then do it all again when you see each other at the next tournament.
Right now the tally is 2-1 to Cornelius, with two wins in the gi versus Hinger's no-gi win at American Nationals.
