Breakdown
Nickal and Pyfer meet as two finishers with different routes to the same result. Pyfer throws slightly more (3.49 significant strikes a minute to 3.34) and carries the bigger knockdown rate, 0.91 per 15 minutes against 0.74. But he absorbs 3.33 a minute and lands just 43% of his strikes, while Nickal lands 59% and gives up only 2.29. The wrestling gap is clear: Nickal attempts 2.11 takedowns per 15 minutes and stops 82% of those against him, while Pyfer stops 66%. Nickal also holds control 31% of the time to Pyfer's 12%. Size is close, with Pyfer an inch taller and Nickal an inch longer in reach.
Our model leans Nickal at 57% to 43% because of three things: his accuracy and defence on the feet, his takedown defence, and his control time edge. Those suggest he can pick when and where the fight happens. Pyfer's Elo (1631 to 1594) and four-fight win streak keep the gap modest, and Nickal has been knocked out once, so Pyfer's power is a real threat. No betting market line is available to compare against.
Key question: can Pyfer land something heavy before Nickal drags him to the mat and starts controlling the fight?
