68% · Decision
  • Santos has proven UFC experience (3 fights) vs Yoo's debut status
  • Santos averages 1.9 takedowns per fight with 73% takedown defense
  • Recent KO win shows Santos has finishing power at 145 pounds
  • Santos' 37% striking accuracy is low but against unknown opposition could be sufficient
Write-up

Santos has significant UFC experience with established metrics while Yoo is making his debut with no UFC data. Santos' 50% takedown accuracy and 1.9 takedowns per fight suggest he can implement a wrestling-heavy gameplan. His recent form shows 2 wins in last 3 fights, including a KO finish. The lack of data on Yoo makes this a calculated risk, but Santos' proven UFC ability gives him the edge.

Write-up

Daniel Santos holds a clear statistical advantage in both striking and grappling, with measurable UFC experience and a high output. JooSang Yoo has no recorded UFC stats, indicating either a debut or minimal top-level experience. Santos' defensive liabilities are offset by his offensive volume and proven ability to mix in takedowns, making him a strong favorite against an untested opponent.
