You can always afford players you can't win without. Think they are considering releasing Flacco ? No. The fact they choose boldin means they think he's replacable.
You mean players like John Lynch? Warren Sapp? Charles Woodson? Vincent Jackson? Or any other player that changed teams?
Baltimore's problem is they have too many good players and can't afford them all. Them choosing to re-sign their Superbowl Winning MVP QB over their 2nd WR doesn't mean their 2nd WR isn't a good player.
