Style Matchup Analysis
Where this game is vulnerable
Exploitable Patterns
Physically larger opponents who can impose size from top
Aggressive pressure passers who can flatten his guard
Wrestlers who can dictate the pace and avoid his guard entirely
Nightmare Matchup
Dalpra's relentless pressure passing and superior size make him the nightmare opponent for Mikey. Dalpra can flatten guards that Mikey relies on, and his passing pace leaves no room for the intricate leg lock setups Mikey depends on.
Closest Calls
Sousa nearly upset Mikey with aggressive guard passes before Mikey found a late leg lock entry.
Engine Insight
Relative weakness: Takedowns (65) is 19 points below their 84 average — opponents strong in this area have the best chance.
Trophy Case
Roosterweight GOAT — first American at that weight
