Pretty sure I don't like this idea but Goodell recently talked about the idea of adding two new teams if no teams end up moving to LA/Southern California. In this Yahoo article, Goodell discussed that adding just one team would create scheduling conflicts including having a team off every week of the season.
"We probably don’t want to go to 33" teams by adding just one new club if a suitable stadium is built in the Los Angeles area, Goodell said. Instead, the league would consider adding two. An odd number of teams would pose scheduling problems, including at least one club being off each week, and would create one division with five teams.
Further speculation mentioned that LA could house two teams, but logic says this would be a tremendous mistake. LA once had two teams and it ended up costing them both teams. There is still question for many of us if LA can even support one team really.
What I really hope though is that this need for a 34th team doesn't equal a team in London. I think it will be a tremendous burden on the league and players with the extra travel and what that does to the players. Plus, who's going to want to leave the country to play there...most of the players are probably going to want to sign with US based teams. I'd rather see a team in Canada than in London. I think adding teams in general is a poor idea though, the number we are at now is perfect.
