3. Baltimore Ravens went with quantity, not quality at cornerback
The Baltimore Ravens moving on from Marcus Peters is far more explainable than Calais Campbell. His age, and injury status have caught up to him a lot quicker, and he remains unsigned for a reason. Campbell signed instantly for a reason. Still, you can argue that the Ravens could have done more to address the position.
They added plenty of names, but could they have tried to use more to get quality? In free agency, the big names were Rock Ya-Sin and Trayvon Mullen. Both these players have been starters and will compete for a starting job. However, they are living off of their draft status and have been up and down in the NFL.
They are younger, and at this point better physically compared to Marcus Peters, but neither has been the answer so far in their NFL careers. They drafted Kyu Blu Kelly in the fifth round, passing on Joey Porter Jr. in round one, and a group of cornerbacks such as Mekhi Blacmon, Jakorian Bennett, Kelly Ringo, and Clark Phillips in round three when they took Trenton Simpson over them.
They also passed on signing bigger-name cornerbacks who exchanged teams such as Shaq Griffin. Stephon Gilmore, Byron Murphy, and Cameron Sutton. However, they went in another direction altogether.
They signed a couple of second-tier free agents and waited until day three, and now they hope that competition will bring out the best. It is possible but riskier than just taking care of the spot.
