Barnett is rated at 1454 — 325 points above Nelson's 1129. Gaps this large usually mean one fighter has been consistently beating better opponents.

Stylistically this is Barnett's submission artist game against Nelson's striker approach. Barnett is most dangerous on the ground, constantly threatening chokes and joint locks, while Nelson brings a versatile approach. Historically these archetypes are dead-even when they collide.

A few statistical edges stand out. Barnett throws significantly more leather — a 2.1 sig. strike per minute gap. Barnett is far more active with takedowns, averaging 1.4 more per 15 minutes. Nelson has tighter striking defense, making opponents miss more often.
