RJ Harris
What our AI said before the fight
Alvin Hines is a UFC-tested heavyweight with 5 fights in the octagon, solid finishing rate (6 of 7 wins by finish), and recent activity through mid-2025. He lands 5.47 sig strikes per minute with 32% accuracy and shows submission threat (3 subs in record). However, he just lost a decision to Jhonata Diniz and absorbs 7.47 strikes per minute—a concerning defensive metric. RJ Harris is a massive red flag: his last fight was in June 2021 (nearly 4 years ago), his record is thin at 3-1, and his only recent activity shows a loss in 2012 to Levi Thompson by submission. Harris has zero UFC experience and appears to be a late replacement or journeyman filler. The gap in recent activity, UFC exposure, and current form is stark.
About these numbers
Market probability is the live crowd consensus from Polymarket, a public prediction market where people trade on outcomes — we read it as a data signal for what the crowd expects, and it updates continuously. AI probabilityis our own model’s independent read of the matchup from fighter data alone; it never sees the market price, which is why the two can disagree.
