(...) tom by KO you think?
Statistically, that's the most likely scenario, but Blaydes probably will be focused on surviving round 1, which would be a small victory and could put more mental pressure on Tom. From the vids on youtube it looks like both are preparing for some ground action. So I wouldn't be surprised if this fight goes differently than Tom's previous fights, but I don't think it'd go to the distance.
Here are the odds for all of the main card fights:
Leon Edwards x1.44 vs. Belal Muhammad x2.80
Tom Aspinall x1.27 vs. Curtis Blaydes x3.80
Bobby Green x1.86 vs. Paddy Pimblett x1.94
Christian Leroy Duncan x1.70 vs. Gregory Rodrigues x2.15
Arnold Allen x1.38 vs. Giga Chikadze x3.05
Not the main card, but Mokaev has decent odds at 1.68 against Kape (x2.18).
