Style Matchup Analysis

Where this game is vulnerable

Exploitable Patterns

1

Physically larger opponents who can impose size from top

2

Aggressive pressure passers who can flatten his guard

3

Wrestlers who can dictate the pace and avoid his guard entirely

Nightmare Matchup

Tainan Dalpra

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

W
Mundials 2022 Rooster Final·2022

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.
