(AP) – It’s the height of summer; the weather is hot and sticky in most of the U.S. – which means it’s time to start getting serious about football. In this case befriending football teams. If there was a trophy for that, the Dallas Cowboys would be champs. They are the first NFL team to hit the 5 million mark in Facebook “likes.” If the team had won the Super Bowl, coach Jason Garrett would get credit. But he has nothing to do with the team setting the Facebook mark. He says he’s never been on Facebook and doesn’t even know what a “like” is.
