Jack Hermansson “The Joker” is a 38-year-old Orthodox welterweight out of Norway, camped at Frontline Academy. The tape read: pocket striker. Career mark 24-10-0 — 4 by KO/TKO, 6 by submission, 14 by decision. Fight IQ grades C+ (63).
What works. Striking defense is the standout at 71 (B). Serviceable pocket defense. Can be found, but rarely walks into the same shot twice. Ground game D on 1.48 TD/15 and 0.37 sub attempts. Striking defense B at 71% / 3.60 SApM. Counter punching D; punching agility D (output × accuracy × age curve). Takedown reaction C+ on 79% TD defense. These are tape proxies — not lab reaction times — built from FightMetric rates, finish shares, and 1 loaded UFC rows.
Where it breaks. Ground game is the soft spot (37, 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 (1 bouts): L Rodrigues (KO/TKO R1). Form index negative over the last 1. Most of the loaded finishes happen before the deep water.

Late on the read. High absorb or a leaking TD defense suggests the first move often belongs to the opponent.
Heavy or economical. Combinations are chosen, not sprayed — opponents can time the entries.
Hips arrive late. A committed wrestler will get them down; the question is what happens next.
Standard UFC durability. Can be hurt, usually recovers if the shot is not clean.
