Watching days late, Walter Stewart had me doing research

I am behind on shows because life gets in the way of my watching, currently watching 8/4 show, Thankfully I can avoid spoilers. But..

Watching Finley v Oleg, walker said Finley is a 31 year vet. I'm looking at my screen saying to myself how? How can he be a 31 yr vet he's maybe mid 30s. So I looked it up & Finley is a 12 year vet but is 31 yrs old. So either Walker made a mistake ( he said it a few times ) or that is the gimmick Finley runs.. he's a 31 yr vet… his age 31 meaning he's been in the business since birth. 🤣 😂
