Breakdown of Flacco's contract:
He has about $30-$51 million as guaranteed money for the first two years while the rest of the guaranteed money is dependent on if he ever gets hurt (fully guaranteed) or not (none guaranteed).
Also the cap hit starts to get brutal after Year 3. Best chance for the Ravens to repeat is next year since its just an $6.8 million hit on the cap.
