"NFL football is nothing more than a high-priced entertainment extravaganza, and has become increasingly dull for serious football fans"
You're insane. Football has never been better or more popular. The league really made some good decisions with realignment and free agency. These are the NFL's glory days.
The quality of play in the NFL these days is miserable -- and I say this as someone who knows more about the game than your typical fan. The wholsesale movement of players under the salary cap and free agency rules has destroyed the basic notion of "team chemistry" in the NFL.
I don't know what the NFL has done in terms of "good decisions," but a tiresome, dull spectacle that provides 10-12 minutes of actual play in a 4-hour television broadcast barely even qualifies as a sporting event anymore.
