Spence actually has a small head. Mikey's head is the size of the moon that Thanos threw at Tony Stark.
Alright, I know the OP fixed his title but seriously let's discuss Miguel Román vs. Ramiro Blanco instead. There's been plenty of Spence vs. García talk in the last few months; everything that can possibly be said, has. Played out. Let's spotlight an underrated but less prominent fight. [/hijack]
No Spence has a huge noggin on a wiry 154 pounder's frame, Mikey has a massive noggin on a stocky 140 pounder dwarf's frame.
Spence has a penchant for fighting dogs, I have seen him fight a medium-sized breed once but it was a mangy old one-eyed pooch that had been beaten and abused by their previous owner but other than that time I've only seen him take on chihuahuas, pugs, miniature poodles, and pomeranians.
