Pre-fight analysis — how we saw it going in

Case for Mederos

Mederos barely wrestles at all, averaging 0.23 takedowns per 15 minutes, so his route is to keep the fight standing and win the striking exchanges outright. His 83% takedown defence is the highest of the two and is what he needs to lean on.

Case for Jones

Jones brings the more varied attack, averaging 3.48 takedowns per 15 minutes alongside a marginally higher striking output. His route is to make Mederos carry weight and fight off his back rather than trade cleanly.

What We Were Watching For

  • Whether Jones commits to his wrestling early or feels out the striking first — he is the only one of the two who shoots with any regularity.
  • Mederos’s 83% takedown defence against the highest takedown rate he has faced on this card.
  • Striking volume is near-identical (5.46 against 5.98 landed per minute), so the separation is likely to come from grappling, not output.
  • Both absorb a similar amount (4.58 against 4.45 per minute), which points to a competitive rather than one-sided exchange.
