It's easy to see how some of these British lads and laddettes might have missed some of the relatively well-known football names that we take for granted over here. They asked these kids who Greg Jennings is. Greg Jennnnnings! Who's the Premier League version of Greg Jennings anyway? Michael Carrick? How many Americans know Michael Carrick? I'll give these teens a pass on not knowing Greg Jennings.
As for the dude who thinks that George Costanza plays in the NFL, though—come on, man. Every English speaking person in the world at least KNOWS of "Seinfeld." Surely you've encountered that name at some point. And you should know it wasn't on Sky Sports.
