And the difference in their structures was clearly visible as Fury stood nearly one-and-half-feet over Barriga, and the former's fist looking as big as the latter's face.
At that point one of Wilder's entourage - as sizeable as Fury's - threw a shove in Fury's direction and those with each fighter responded by doing the same until they were gradually separated as Fury removed his shirt and continued to shout.
"Mark my words, I will knock him out", said Fury, the former world heavyweight No1. You plan one thing and you get in there and it all changes.
It is set to be a busy week for the American boxer, as he ploughs full steam ahead into his pre-fight obligations ahead of the weekend's bout with Fury.
"I don't think we should bring this fight into a battle of races, or a battle of cultures or all that", Fury said. "That is what really happens, but I have been like this since day one, this ain't an act".
"Saturday night you've got a different beast". He took a lengthy hiatus following his lineal heavyweight title victory over Wladimir Klitschko in 2015.
Klitschko looked a calm and composed figure back then, just like Wilder is now but it was the Mancunian that came out on top. "I'm not going to make that mistake; I'm not going to lose my purse", Fury said.
"I'm staying in downtown LA but if you go five minutes down the road there's like - I don't know - thousands of homeless people".
"I believe all kids should make their own money in life because if they don't, they won't appreciate it". Fighting's all I've ever done.
"I'm just an outsider with an opinion but it's a situation that is happening all over the world, especially in the United Kingdom as well".
