What you are describing is a trademark. A trademark can be a word, phrase, symbol, logo, design or image. Companies do not buy the trademark but register it so no one else can use it without their permission.
Assuming you even need permission (which is not always true), you can contact the NFL for information about the requirements for your use. Many uses do not require any permission at all, depending upon which mark and how it is to be used. For example, the name of the team is a trademark, but you would not need permission to simply put that name into a list of names, or other description of the team, for example.
It's not something I would risk without permission. Trademark, unlike copyright, must be defended or the holder risks loss of trademark status through dilution.
Not without your permission.
