Fight IQ
Knows the assignment. Game plans hold up for 15 minutes; the adjustments are incremental, not chaotic.

Counter punching
This is a first-strike, pressure profile more than a counter. Wins come from owning the center, not waiting.

Striking defense B at 55% / 2.37 SApM. Counter punching C; punching agility B+ (output × accuracy × age curve). Takedown reaction B on 85% TD defense. These are tape proxies — not lab reaction times — built from FightMetric rates, finish shares, and 6 loaded UFC rows.
Where it breaks. Ground game is the soft spot (14, D). Thin offensive ground game. Wins come standing; once taken down this fighter is hunting a stand-up, not a sweep chain. Opponents who force wrestling and keep the fight on the fence have historically been the ones who make this résumé leak. Losses lean decision more often than a highlight — the issue is usually control of minutes, not a glass jaw.
Recent tape (6 bouts): L 4881997 (KO/TKO R2) · W 5070502 (KO/TKO R1) · W 5078112 (TKO (Punches) R1) · W 4421059 (Decision - Unanimous R3) · W 5282140 (TKO (Punches) R1). Form index positive over the last 5. 2 of those wins reached the championship minutes — cardio and late IQ are real.
Thin offensive ground game. Wins come standing; once taken down this fighter is hunting a stand-up, not a sweep chain.
Serviceable pocket defense. Can be found, but rarely walks into the same shot twice.
This is a first-strike, pressure profile more than a counter. Wins come from owning the center, not waiting.
Average-plus reactions. Gets touched, but rarely frozen in place when the shot or the shot-to-takedown comes.
Enough snap to score and to threaten. Not a blur, but the volume is organized.
Can stuff the first shot. Chain wrestling and the second entry are the real test.
Gets through fire. Rarely finished by strikes; the later minutes are still theirs to win.
