Why the model leans this way

Duncan 55 — the tape favors pocket striker

Christian Leroy Duncan is the model side at 54.6% because the largest live edges sit where this fight is likely to be fought. Grappler historical edge: Allen (ground 57) into Duncan (TD reaction 68). Open-stance look favors the southpaw / switch side slightly. Ground game is the clearest separator: Allen 57 (C) vs Duncan 18 (D). Allen brings 1.6 TD/15 and 14 sub wins into Duncan's 83% takedown defense.

    Timing & reaction

    Duncan

    Duncan 73 (B) vs Allen 63 (C+). The reaction proxy — defense plus absorb plus knockdown timing — sits with Duncan.

Path · Allen

Allen has to wrestle early, chain the second shot, and make Duncan defend the neck instead of throwing. It is the only reliable flip if the pocket goes cold.

Path · Duncan

Duncan has to stuff the first takedown (68 TD-reaction), keep this standing, and hunt a pocket that grades 64 on defense. Wrestling is the death lane.

A one-score fight on the model. Any three-minute pocket explosion or a stuck takedown against the grain wipes a lot of this number.

Any three-minute pocket explosion or a stuck takedown against the grain wipes a lot of this number. These trait marks are derived from FightMetric rates, career method shares, and loaded bout rows — reaction time and agility are proxies, not stopwatch numbers. The model folds the same scores into win probability, so a hole on this card is a hole in the percentage.
