Style Matchup Analysis

Where this game is vulnerable

Exploitable Patterns

1

Physically stronger opponents who can impose wrestling and avoid pulling guard

2

Pressure passers who can flatten her guard and deny space for submissions

3

Athletes with superior conditioning who can push the pace in later rounds

Nightmare Matchup

Gabi Garcia

Garcia's massive size and strength advantage makes it nearly impossible for Dern to impose her technical guard game. Dern's submissions from bottom are neutralized by Garcia's ability to simply power through positions.

Closest Calls

L
Mundials 2015 Lightweight Final·2015

Nicolini's guard passing and experience edged Dern in a competitive final between two elite lightweights.

Engine Insight

Relative weakness: Takedowns (72) is 11 points below their 83 average — opponents strong in this area have the best chance.
