Domestically, American football has never been more popular (or prosperous) than it is today - yet questions continue to circle among the ownership class of the NFL as to how the pro game can continue to grow outside the confines of its current 32-team franchise structure.

While the feasibility of pursuing more club expansion within the US is hotly debated, there is no denying that the true future of the league's fortunes rests on its ability to more reliably tap into the massive fan fervor for pro pigskin building in international markets.

Ben Issacs ("The American Football Revolution: How Britain Fell in Love with the NFL") makes the case that the UK might be one of the most logical regions to put on the league's shortlist - buttressed by a surprisingly strong history of interest in and support for the game - especially in London, where nearly three dozen regular season games have been played since 2007.

In fact, the British Isles have been fascinated with American football for much longer than that - and Isaacs takes us through some of the evidence, including: the NFL's American Bowl pre-season exhibition series during the 1980s; the post-season 1984 USFL Wembley Stadium matchup between the champion Philadelphia Stars and the Burt Reynolda/Tim Bassett-owned Tampa Bay Bandits (for the long-forgotten "Jetsave Challenge Cup"); the ill-fated league-sponsored World League of American Football (with the 1991 World Bowl champion London Monarchs); and the reconstituted NFL Europe/Europa and its still-revered Scottish Claymores.
