Ketlen Vieira (point fighter, defensive wrestler, counter striker) against Gregory Rodrigues (power puncher, pressure boxer, opportunistic) is a UFC women's featherweight matchup in —. The independent model puts Rodrigues around 57% — a medium confidence number, not a betting line. The largest factor from 50/50 is striking skill (distance & pocket): Vieira striking rating 1580 vs Rodrigues 1740. Weighted by estimated standing time (78%).

Where this is fought matters. Estimated grappling share is 22%. Vieira lands 3.4 significant strikes per minute at 44% accuracy with a 1.4 takedown average; Rodrigues is at 5.2 / 51% / 1.6. Takedown defense sits at 72% versus 61%. Reach is 68" against 75" — counted only if the longer fighter actually lives at range.

Vieira's primary path: Chain takedowns on Rodrigues's 61% defense, hold mat time, and win the control/attrition round. Failure mode: Getting drawn into Rodrigues's preferred range and losing the minute-winning. Rodrigues's primary path: One clean counter or lead hook as Vieira enters. Power is the shortcut; it is not a plan by itself. Failure mode: If the first takedown lands, Rodrigues may spend the round on the fence or on their back.

The swing variable is simple: If Vieira cannot keep this on the mat in the first eight minutes, Rodrigues's striking becomes the fight. The model does not start from a sportsbook. If DraftKings or Fanatics disagree, that disagreement is the point of the page.
