The guy squirting water into Zach Ertz’s mouth is Joe O’Pella. He’s an athletic trainer that’s been with the team for over 15 years at this point. NFL teams don’t really have water boys, athletic trainers are usually the ones responsible for having water on the practice field and during games, but this post is absolutely hilarious. A guy who rehabbed my ACL tear in my second year, has a masters degree from Pitt, and has years of experience keeping Eagles players healthy and on the field being called a “Waterboy” is crazy, and I’m already giving him shit for it, but good lord this post is so wildly misleading. Either way, thought I’d clear the air, that the people with Water Bottles during games actually serve much bigger roles on NFL Teams.
