Fight IQ
Knows the assignment. Game plans hold up for 15 minutes; the adjustments are incremental, not chaotic.
Durability
Standard UFC durability. Can be hurt, usually recovers if the shot is not clean.
Counter punching
Limited counter threat. Opponents can miss without paying a finishing tax.
Timing & reaction
Late on the read. High absorb or a leaking TD defense suggests the first move often belongs to the opponent.
Punching agility
Heavy or economical. Combinations are chosen, not sprayed — opponents can time the entries.
Reinier de Ridder “RDR” is a 35-year-old Southpaw light heavyweight out of Netherlands, camped at American Top Team. The tape read: hybrid who can change levels — southpaw. Career mark 21-4-0 — 2 by KO/TKO, 13 by submission, 6 by decision. Fight IQ grades B+ (76).
What works. Fight IQ is the standout at 76 (B+). Knows the assignment. Game plans hold up for 15 minutes; the adjustments are incremental, not chaotic. Ground game C on 2.56 TD/15 and 0.55 sub attempts. Striking defense C at 54% / 2.64 SApM. Counter punching C; punching agility C (output × accuracy × age curve). Takedown reaction C+ on 75% TD defense. These are tape proxies — not lab reaction times — built from FightMetric rates, finish shares, and 6 loaded UFC rows.
Where it breaks. Counter punching is the soft spot (50, C). Limited counter threat. Opponents can miss without paying a finishing tax. Opponents who out-speed the first exchange and never stay on the centerline 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 4835137 (Decision - Unanimous R3) · L 4025699 (KO/TKO R4) · W Whittaker (Decision - Split R5) · W 5061870 (KO/TKO R2) · W 3943695 (Submission 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.
Eats more than a championship pocket should. High SApM or a porous guard will get taxed against power.

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.
