Let's set aside the conversation on rules, ratios, etc. and have a little fun coming up with names for this new CFL-XFL adventure. Whether it's a full blown merger or a partial interleague schedule, there's a great opportunity for a new brand to emerge.
Ideas that come to mind...
Major League Football
World Football League or World League
Global Gridiron Football
Gridiron Football International
North American Football League
As an aside, I wonder if the model we will see is a new umbrella league with the CFL and the XFL existing as separate entities underneath it? Think the structure of junior hockey.
