Joseph was among an eight-player group of ambassadors, including Akiem Hicks of the Bears and Mario Addison of the Panthers, who spent this week promoting their sport instead of vacationing on the beach or engaging in Fourth of July activities in the states. Each representative will have a team participating in the 2019 London Games, a league fixture since 2007.
In addition to serving as an honorary coach during the 2019 NFL Flag Championships on July 3 -- a competition in which his team finished the runners-up -- Joseph conducted various interviews, combine-esque drills, and clinics for kids, all in the name of increasing the NFL's presence across the pond.
"This has been a great experience for me," Joseph said Wednesday via John McClain of The Houston Chronicle. "I've been so impressed with the kids. They're eager to learn, and there's definitely talent here. They want to be coached up."
As evidenced by the last part of his statement, the two-time Pro Bowler didn't hesitate to put on his scouting hat in the midst of his overseas trip. When asked if the NFL could see an influx of U.K. players in the coming years, Joseph expressed that he likes the chances.
"The NFL's doing so much to promote our football over here. You find a talent pool like they have here, and they start to work at getting better, and, in time, I think you'll see several players in the NFL coming from here," he said.
Should Joseph's prediction be true, efforts like those he and his colleagues contributed to in London could have a significant influence as the NFL continues to evolve.
