As usual, the Ravens weren’t big movers and shakers in the free-agent market this offseason, but general manager Ozzie Newsome did pick his spots to augment the roster with veteran talent.
Looking to improve the secondary as well as replace backup quarterback Tyrod Taylor, the Ravens made three key veteran signings they hope will pay dividends during the 2015 season.
Below is a look at each one as you can vote in our poll and comment below on which signing will pay the biggest dividends for the Ravens:

S Kendrick Lewis
Age: 27
Contract: Three years, $5.4 million
Synopsis: The former Texans safety was part of a game of musical safeties in the AFC this offseason as ex-Raven Darian Stewart signed with Denver and former Bronco Rahim Moore landed with Houston. Considering their issues at safety last year, the Ravens hope Lewis can play an effective deep center field after the likes of Stewart and Terrence Brooks allowed too many balls to go over their head. During spring workouts, Lewis consistently worked with the starting defense while Will Hill and Matt Elam rotated at the other safety spot. Of their three biggest free-agent signings, the Ole Miss product projects to receive the most playing time as defensive coordinator Dean Pees would like him to provide an upgrade over Stewart, who underwhelmed for much of the 2014 season.
QB Matt Schaub
Age: 34
Contract: One year, $2 million
Synopsis: The Ravens and their fans pray that the only impact Schaub makes will come in the meeting room and on the practice field as a source of knowledge and experience to aid franchise quarterback Joe Flacco. You never want to draw too many conclusions from spring practices, but the former Texans quarterback didn’t inspire much confidence based on his play as he struggled to connect with receivers consistently and threw too many interceptions. If Schaub sees extensive playing time, it clearly means something has gone horribly wrong for the Ravens during the 2015 season. Baltimore invested real money in a backup quarterback for the first time since 2010, but I’m not convinced that Schaub will give them a much better chance to win if he needs to play than Taylor did the last couple seasons.
CB Kyle Arrington
Age: 28
Contract: Three years, $7 million
Synopsis: With the Ravens’ extensive injuries at the cornerback position a year ago, Newsome couldn’t afford to go into the 2015 campaign without an established veteran to go with Jimmy Smith and Lardarius Webb in the nickel defense. The former New England cornerback is very solid defending the slot and allows Pees to keep Webb on the outside. This signing takes pressure off the likes of fourth-round rookie Tray Walker, Rashaan Melvin, and Asa Jackson on the depth chart, but the key to the secondary’s success will be the ability of Smith and Webb to stay on the field. Arrington will have to perform and isn’t a great fit playing outside, but the Ravens paid a very reasonable price when you remember some of the bloated contracts given to free-agent corners at the start of free agency.
