Path · Vieira
Vieira has to wrestle early, chain the second shot, and make Bryczek defend the neck instead of throwing. That is the percentage path.
Path · Bryczek
Bryczek has to stuff the first takedown (64 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.
Style and location. Wrestling entries, fence control, and mat time should decide the scorecards — or the finish. Vieira is built as: Hybrid who can change levels. Bryczek is built as: Pocket striker. Fight IQ delta is +4 toward Vieira — that is composure, win-lane diversity, and whether they solve a second problem when the first look dies.

The finish path leans the mat (48% submission). Once a takedown sticks, the neck becomes the whole fight. 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. 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.
