Expansion, especially internationally is the NFL's next move. Bflo will stay because it is the gateway to the Canadian market. Mexico City and London are good candidates for the future. Maybe even A German team after (the one other place NFL Europe was a success and that gives you 4 new teams TO, MC, LON, Hamburg which could make divisional play more even and acceptable) the NFL is a business that will have to expand. Closing out on old franchises is a thing of the past IMO as history is a big part of the story that they will be selling. I.E. Man U, Manchester is not a giant place but a rather smallish formally industrial Knob that has a history (and a very super rich owner). TV revenues make the story much more important than the actual place. Winning would help Bflo's cause lol.
Outside the boarders is the most sense-able way to go. Soccer is a great and fairly easy model to follow and at some point these greedy bastards are going to realize it (if they haven't already, which I think they have but they don't seem to agree on the best way to make the expansion happen, yet). As far as the talent being spread thin, yeah it would be. The QB issue could be solved by changing rules a bit though. They really need to expand the league in a few ways the NCAA is out molded and eventually will have to be changed to make a new structure. Little leagues internationally would be a great way to get the game a more international face. I have a ton of ideas for them, they should hire me
