What they do well

  • Durability

    Gets through fire. Rarely finished by strikes; the later minutes are still theirs to win.

  • Fight IQ

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

  • Punching agility

    Enough snap to score and to threaten. Not a blur, but the volume is organized.

Where they leak

  • Ground game

    Thin offensive ground game. Wins come standing; once taken down this fighter is hunting a stand-up, not a sweep chain.

  • Counter punching

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

Scouting report

JooSang Yoo “Zombie Jr.” is a 32-year-old Orthodox featherweight out of South Korea, camped at Tiger Gym. The tape read: volume pressure striker — high-iq problem solver. Career mark 9-1-0 — 2 by KO/TKO, 1 by submission, 6 by decision. Fight IQ grades B+ (81).

What works. Durability is the standout at 85 (A). Gets through fire. Rarely finished by strikes; the later minutes are still theirs to win. Ground game D on 0.00 TD/15 and 0.00 sub attempts. 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.
