The NFL is into worldwide expansion, witness games played in London and Mexico in recent years. A pro league even surfaced in India in 2012. I'm sure they have their eyes on China. My inquiry is why the NFL never invested in the Canadian Football League, it's established, has a loyal fan base and has been around for years. Players like Warren Moon and Jeff Garcia had their starts in the CFL. Currently Cameron Wake has had a big impact with the Dolphins. And if researched you will find many more. Why not get into partnership with the CFL? It would take years to build a minor league for the NFL and would be a financial loss while it was being developed.
