Breakdown
Radtke and Thompson are close to opposites in how they work. Thompson is the volume striker, landing 4.01 significant strikes a minute to Radtke's 2.66, and he has three inches of height and reach on him. Radtke is the steadier all-rounder. He absorbs less (2.62 a minute vs 3.01), shoots 1.85 takedowns per 15 minutes at 41%, and holds control for 47% of his fight time. Thompson rarely wrestles and has defended only 63% of takedowns against Radtke's 75%. Both men have been knocked out twice, and Radtke's finish rate is higher (39% vs 27%).
Our model leans Radtke at 55%, mostly because of wrestling and control. His takedown game and 75% takedown defence give him a way to neutralise Thompson's range, and his 67% smoothed win rate and two-fight win streak beat Thompson's three-fight skid. Thompson's higher Elo (1575 vs 1545) keeps it close. The market sees it the other way, with Thompson at 54%, a nine-point gap. The likely reason is that Thompson's 22 UFC fights against top competition carry weight the model may undervalue. The model includes layoff and age, but may underweight Thompson's 490 days out and age of 43.8, as well as Radtke's age of 36.4 and 217 days off.
Key question: can Radtke get Thompson to the mat often enough to blunt his volume, or does Thompson's range keep the fight standing?
