Tale of the tape

• Record: Allen Frye Jr. 6-1-0 · RJ Harris 6-0-0
• Age: Allen Frye Jr. 28 · RJ Harris 28
• Height: Allen Frye Jr. 6'4" · RJ Harris 6'6"
• Reach: Allen Frye Jr. 80" · RJ Harris 80"
• Stance: Allen Frye Jr. Orthodox · RJ Harris Orthodox
• Listed weight: Allen Frye Jr. 242 lbs · RJ Harris 262 lbs

Reach is close to even (80" to 80"), so neither fighter starts with a length edge and the striking exchanges begin from the same distance. Both fight orthodox, so lead hands mirror and the rear-hand exchanges are conventional. Listed weights differ: RJ Harris at 262 lbs to 242 for Allen Frye Jr.. Listed weight is a roster figure, not a weigh-in, so it is a note rather than an edge.

Style and statistical matchup

Allen Frye Jr. lands 2.2 significant strikes per minute at 38% accuracy; RJ Harris lands 9 at 57%. That 6.8-per-minute gap in RJ Harris's favour is a real pace differential: over three rounds it compounds into a scorecard edge unless the lower-volume fighter is landing the more damaging shots. On the other side of the exchange, Allen Frye Jr. absorbs 4.27 per minute with 36% striking defence and RJ Harris absorbs 6.6 with 56%. RJ Harris's 20-point defence edge is the number to hold against the pace figures: it decides how much of the opponent's output actually lands.

On the ground, Allen Frye Jr. averages 0 takedowns per 15 minutes at 0% accuracy and defends 0% of attempts against him; RJ Harris averages 0 at 0% and defends 0%. Neither fighter wrestles much by the averages, which points to a fight decided on the feet and makes the striking figures above the ones that matter.

All of these are career-to-date PropSports snapshots at capture, not as-of figures for this bout: they describe each fighter across every opponent, which is why the archive form above is read alongside them rather than replaced by them.

Round-level stats exist for 3 archived rounds of Allen Frye Jr.'s: 33 of 86 significant strikes landed (38%), 11 per round, 0 of 0 takedowns, 7:55 of control time. Round-level stats exist for 1 archived round of RJ Harris's: 15 of 26 significant strikes landed (58%), 15 per round, 0 of 0 takedowns, 0:10 of control time and 1 knockdown. Those samples are small and uneven, so they colour the career averages rather than override them.

What could break the angle

Start with what is missing. Allen Frye Jr. has only 1 archived UFC bout in the PropBetEdge database, so the form read is thin. RJ Harris has only 1 archived UFC bout in the PropBetEdge database, so the form read is thin. Career averages are career-to-date snapshots at capture; they include fights outside this matchup context and are not as-of figures. There is also no odds snapshot in PropBetEdge data for this bout, so nothing above can be checked against a market yet; the read describes what to look for, not where value sits. A late weigh-in miss, a replacement or a change in scheduled rounds would each invalidate parts of it.

Final read

On the data, neither fighter carries a material edge into this one; the tape is close and the archive does not separate them. The uncertainty is mostly about coverage: archive shorter than 3 bouts for Allen Frye Jr. and RJ Harris. What to monitor: the three-round format holding, the weigh-in, and once a price exists, where the significant strikes market opens relative to this read. No model price or market line exists in PropBetEdge data for this bout, so this is not a pick; the Bettor's Edge panel above carries the impact score and the markets connected to the evidence.
