The NFL, being the NFL is always looking for more ways to squeeze more money out of anyone and everyone any way they can. I suspect this is the model for any big business in this country but the NFL sometimes seems to take things to a new level. With that in mind they have said in the past that they will eventually look towards additional expansion. I personally think we are good with 32 teams but money, even for the NFL will always trump the quality of the product on the field.
I came across an article that was posted to Yahoo Sports via a site I have never heard of, Bon Voyaged.
