Leandro Lo leads Keenan Cornelius 6 to 2 across 8 recorded meetings, and the shape of that record tells you most of what you need to know. Both wins for Cornelius came in 2014, at the 2014 IBJJF New York Pro Championship final and in the Round of 16 at the 2014 World Jiu-Jitsu IBJJF Championship. From there Lo won the next stretch, including quarter-final meetings at the 2015 and 2016 World Championship and semi-final wins at the 2018 European Jiu-Jitsu IBJJF Championship and the 2019 World Championship.

Every one of these matches was decided by points or by decision, not by submission. That fits how the two grapplers score their wins overall. Lo finishes 21% of his recorded wins, and Cornelius finishes 62% of his, but when they met each other the finishes never came. These were long, positional gi battles between two of the top medium-heavy and heavy competitors of their era.

The stylistic gap shows up in their favorite finishes when they do submit people. Cornelius leans on the Armbar, his most frequent finish with 22 wins on record. Lo's go-to is the Cross Collar Choke with 15 wins. Against each other, neither weapon mattered, because the meetings stayed on the scoreboard.
