Style Matchup Analysis
Where this game is vulnerable
Exploitable Patterns
Physically stronger opponents who can impose wrestling and avoid pulling guard
Pressure passers who can flatten her guard and deny space for submissions
Athletes with superior conditioning who can push the pace in later rounds
Nightmare Matchup
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
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.
Trophy Case
Black belt title before UFC career
Featherweight
