The Ravens aren’t anti free agency. They are anti relying on it to build the crux of their roster. They are anti getting in bidding wars with teams with unlimited cap space. They are anti paying top-shelf prices for middle-tier players.
The Ravens don’t traditionally sign a lot of free agents. In fact, they are near the bottom of the league in recent years in the number of outside free agents that they have signed. However, they’ve always shown a willingness to make a selective foray or two into the open market when there are needs to be filled and perceived good value to be had.
