The NFL is the one major sports league in this country that I could see expanding again. Every other league is at a good number or could really stand to contract some teams. That being said, I'm not a fan of moving up to 34 teams and playing 18 games, if only because I like the NFL the way it is and don't want to see any changes.
If I could I'd just get rid of all proffesional sports teams in Florida. THey just dont care. LA doesn't care either for football go to San Antonio/Oklahoma City/New Mexico heck add another team to NY...Just a city where people will notice...
