The NFL has well and truly landed in England this autumn, after the Indianapolis Colts lost 27-30 to the Jacksonville Jaguars at Wembley Stadium earlier in October.
And with the New York Giants taking on the LA Rams this Sunday at Twickenham, before a final game between the Washington Redskins and the Cincinnati Bengals at Wembley again, could American football one day become the UK's national sport?
Well just in case it does, we thought we'd better check to see whether the athletes of more quintessential British sports have the transferable skills to make it with an egg-shaped ball.
Alex Iwobi has enjoyed a busy 12 months, breaking into the Arsenal first team against Barcelona last season, becoming one of the first names on the team sheet, but would his north London team-mates be suited to throwing the ball rather than kicking it?
Speaking to us at the NFL House opening party, Alex said: "To be fair, Per Mertesacker is very strong, and I'm sure with his arms he'd be able to throw a good pass!"
But of his own chances, Alex was not so sure.
"Per may be up there, but I'm 100% down there," he continued. "I'm slow, and when it comes to catching I can't focus on when it's coming to me so I'd miss the ball.
"But all the people who are fast would be okay: Hector Bellerin, Theo Walcott, Danny Welbeck, Alex Oxlade-Chamberlain."
Next up, England cricketer Jason Roy. The Surrey batsman was also confident that, if needs be, cricketers would be up to the challenge.
"Ben Stokes would make a decent NFL player I reckon," says Jason. "He's got that edge to him, got a good arm - there's a few quick sprinters in there like Chris Jordan as well, he's pretty quick."
So footballers and cricketers seem like they might be okay - but of all the sports, Greg Rutherford makes a very appealing case for track and field events being best suited to the sport of touchdowns and half-time shows.
"Marquise Goodwin, who plays for Buffalo, was in the Olympic long jump final with me in 2012," Greg told us at the NFL event.
"My only experience is when I was having a bit of fun out there trying it as a wide receiver. But I think track and field and the NFL have a really close relationship.
"It probably suits most (track and field athletes), just not the joggers. Mo (Farah) is a tiny guy, can you imagine the poor bloke getting hit? He'd get broken in half! Mo is obviously one of the greatest athletes of all time, just not quite suited to American football I imagine."
So, should American football come to prominence on these shores, it looks as though at the very worst, Per Mertesacker, Ben Stokes and Greg Rutherford will be able to put together some kind of team.
But for Mo, it's a no we're afraid.
