Vettori -130 odds are correct and shouldn't deservedly go wider.
I like Vettori's 1st-strike and counter offense that changes seamlessly. It's a forward, technical brawl that wins fights because of great reaction time, good defense fundamentals, quick/ combination punching and conditioning. Though the high energy naturally fades Vettori a bit in the 3rd, I wouldn't worry about him dropping the round. He could improve by employing variety (Like Jack), but the punch-heavy style is dialed enough to be formidable, for now.
What Hermansson does well is blending elusive movement with quick jabs, kicks and 1-2's, but I'm afraid the shine of his high output vanishes when he doesn't have a plodding opponent to measure offense against. Regardless, this is all precursor to takedowns, which he's good at the singular attempts, but he suffers a bit by not chaining methods to secure the ground fight.
Vettori has brick strength, Hermansson with wiry, leverage strength and they both scramble quick, but I think Vettori could edge in grappling early. Even if Hermansson gets Vettori down, Vettori presses for space and grabs a leg to reverse, but this is the worry. Hermansson is rabid for snatching things within his grasp, but I have to assume Vettori and Kings coaches are wise to one of Hermansson's most successful chokes and won't give the invitation.
Vettori looks good on tape, but Hermansson has fought and defeated top 10 and he should still be considered to be in his prime at 32.
Vettori isn't the Santos or Cannonier danger that defeated Jack previous and 5 rounds favor Hermansson, who prides himself on conditioning.
Good fight.
