Eagles owner Jeffrey Lurie released a statement regarding the announcement that Super Bowl 2014 would be played in the New York stadium. He obviously supported the vote because the Eagles are also a cold-weather city who would also like to host a Super Bowl.
"Hosting the Super Bowl here in Philadelphia would be a great experience for our fans across the city and region. We certainly have an outstanding combination of assets including an expansive infrastructure built to host large events and conventions. With that said, we realize that warm weather options may always have the advantage when it comes to hosting the Super Bowl. However, if the league supports more northern games, we would pursue."
Jason from SB Nation's Bleeding Green Nation doesn't see this as much about a cold-weather vs. warm-weather issue as it is a new stadium issue.
It's not the desire to have a cold weather Super Bowl that motivated the NFL to put the game in New York. It was a reward for getting a new billion dollar stadium built. I suspect that the prospect of hosting a Super Bowl will be used as leverage to get cold weather cities all over the NFL to help their teams build new stadiums.
