I would be completely and utterly stunned if the Baltimore Ravens allowed Joe Flacco to leave but there's the slim possibility that it could happen. Flacco is set to be a free agent but the Ravens, if they can't work out a longterm deal with him, will place the franchise tag on him.

There are two kinds of franchise tags: 1.) non-exclusive and 2.) exclusive. The non-exclusive tag, which is what most players get, means another team can offer Flacco a contract and if the Ravens decline to match it the other team can give up two first round picks and acquire Flacco. The exclusive franchise tag means the player can't negotiate with other teams.
