Jiri Prochazka
70% · KO/TKO
  • Prochazka lands 1.65 more strikes per minute with 17% better accuracy (55% vs 38%)
  • 4-inch reach advantage combined with orthodox vs southpaw creates distance control
  • Rountree has never landed a UFC takedown while defending only 58%
  • Prochazka's grappling threat (0.72 TD avg) adds dimension Rountree cannot counter
Write-up

Prochazka's significant advantages in volume (5.38 vs 3.73 SLPM), accuracy (55% vs 38%), and reach (4 inches) create a striking mismatch. His 60% takedown accuracy provides a grappling threat that Rountree (0 takedowns landed in UFC) cannot match. Both lost to Pereira by KO, but Prochazka's overall skill set and recent win over Rakic show superior recovery.

  • Striking volume/accuracy advantage for Prochazka
  • Reach advantage (+4 inches) for Prochazka
  • Rountree's lower defensive metrics and inactivity in grappling
Write-up

Prochazka's higher striking volume (5.38 SLPM vs 3.73), superior striking accuracy (55% vs 38%), and greater finishing instincts give him an edge in a high-paced striking battle. While both fighters are defensively vulnerable, Prochazka's reach advantage (+4 inches) and experience at a higher level suggest he is more likely to land decisive strikes. Rountree's low grappling threat and susceptibility to pressure further favor Prochazka's aggressive style.
