In less than five days, NFL free agency will commence.
Some players will leave their current team to join a new one. Other players will end up returning to the same team they've been with for years.
Besides McKinnie, those other players all play defense. That means by the time the 2013 season begins, the Ravens could have lost 36.3 percent of their defensive starters from a year ago.
Conversely, the Ravens' offense set a team record in 2012 for the most points scored in a regular season (398).
That means they now have $12,289,237 in cap space.
With this many needs and not a lot of financial flexibility, the Ravens will only be able to sign so many free agents.
Here's a look at which unrestricted free agents the Ravens should target in free agency.
