  • Jandiroba went 6-1 against common opponents while Dern went 2-5, including Jandiroba submitting Lemos while Dern lost
  • Jandiroba's 73% takedown defense vs Dern's 30% - massive advantage in grappling exchanges

Write-up

Jandiroba's superior common opponent record (6-1 vs Dern's 2-5) reveals a significant skill gap. She submitted Amanda Lemos three times while Dern lost to her. Jandiroba's 73% takedown defense vs Dern's 30% is crucial in this grappling matchup. While both are submission specialists, Jandiroba's better striking defense (57% vs 51%) and superior cardio from her 5-fight win streak should control position and win rounds.

  • Superior takedown defense and grappling control by Jandiroba
  • Dern's low takedown accuracy and poor takedown defense (30%)
  • Jandiroba's better performance against common opponents
Write-up

Jandiroba holds a clear edge in grappling control and takedown defense, while Dern struggles to secure takedowns (16% accuracy) and often absorbs more strikes than she lands. Jandiroba's superior defensive metrics (57% striking defense, 73% takedown defense) and her track record against common opponents suggest she can neutralize Dern's submission threat and control the fight positionally. Both are elite grapplers, but Jandiroba's more well-rounded skill set and better fight IQ should lead her to a competitive decision win.
