The temptation with this fight is to treat 13.54 significant strikes per minute and 2.25 knockdowns per fifteen as settled facts about who these men are. They are not — the published career rates include two UFC fights and one DWCS appearance each, totalling 32:26 and 20:00 respectively. McMillen's output figure is heavily loaded by a single record-setting performance; strip out the Montes fight and the number would look very different. Rahiki's knockdown average includes his DWCS stoppage as well as his two UFC finishes. Both are real, both are extraordinary, and both carry the widest uncertainty bands on the page — which is precisely why a matchup between the two most impressive statistical profiles on the card produces a 56-44 line rather than a 70-30 one.
Every measured grappling statistic in this fight says nothing happens on the mat: 0.00 takedowns per fifteen for both, 0% accuracy for both, 0.00 submissions per fifteen for McMillen. And yet five of McMillen's eleven career wins are submissions, all in Round 1, all chokes. The resolution to that contradiction is medical rather than technical — he spent the two years before his UFC debut with a pinched sciatic nerve that made grappling impossible, and has fought only twice since it cleared, both times choosing to strike. A fighter does not lose three guillotines and two rear-naked chokes from his skill set because he skipped them for two fights. Meanwhile Rahiki's published 100% takedown defence includes DWCS and has a limited sample. The most likely single surprise in this fight is a grappling sequence that neither man's UFC statistics predict.
Strip everything else away and one structural fact remains: McMillen has won two third rounds, including a UFC-record volume performance that ended in a stoppage. Rahiki has won zero, and his only trip past the third in his career was a Round 4 guillotine on a regional Australian card in May 2025. Both men absorb well above the divisional average, so the fight getting late is not neutral — it is a measurable advantage for the man who has been there and a measurable unknown for the man who has not. In a fight where 81% of simulations end inside the distance, the 19% that do not are heavily weighted toward one side.
