2022 – ILB Roquan Smith

After a contract impasse with the Bears, Smith was traded to the Ravens in October of 2022 in exchange for linebacker A.J. Klein and second-and-fifth-round picks. Smith immediately became a defensive anchor for Baltimore, making first-team All-Pro and agreeing to a five-year contract extension. Smith's intensity and leadership is contagious, and at age 26, he appears destined for a career that will rank him among the franchise's legendary players. "It's one of the all-time great trades that we've made," Head Coach John Harbaugh said on the one-year anniversary of the trade.

2010 – WR Anquan Boldin

In March of 2010, the Ravens acquired Boldin and a fifth-round pick from the Cardinals in exchange for third- and fourth-round picks. Boldin played three stellar seasons for the Ravens as one of the NFL's toughest targets, catching 186 passes for 2,645 yards and 14 touchdowns. Known for his clutch and tough play, Boldin caught 22 passes for 380 yards and four touchdowns during Baltimore's four-game playoff run to a Super Bowl victory in 2012. The Ravens then traded Boldin to the Detroit Lions after the 2012 season for a sixth-round pick.

2019 – CB Marcus Peters

Six weeks into the 2019 season, the Ravens acquired Peters from the Rams in exchange for linebacker Kenny Young and a fifth-round pick. Peters was an instant difference-maker with a pick-six in his Ravens debut against Russell Wilson, sparking a victory in Seattle. Peters' playmaking and instinctive ball-hawking helped Baltimore to a franchise-best 14-2 regular season in 2019, and he remained a key member of the secondary as a starting corner through the 2022 season. He had nine picks, including one that sealed a playoff win in Tennessee in the 2020 season, in two-and-a-half years with the Ravens.

2020 – DL Calais Campbell

In March of 2020, Baltimore acquired Campbell from the Jaguars in exchange for a fifth-round pick. He made the Pro Bowl in his first season with the Ravens and helped them reach the divisional round of the playoffs. Campbell spent three seasons with Baltimore as a respected team leader, making an impact as a pass rusher, run defender and special teams standout.

2006 – QB Steve McNair

The Ravens acquired McNair in exchange for a fourth-round pick in the 2007 draft. The former Most Valuable Player had a stellar first season with the Ravens, leading them to a 13-3 record and a first-round playoff bye, completing 63% of his passes with 16 touchdowns and 12 interceptions. After the Ravens were upset by the Colts in the divisional round, McNair struggled with injuries in 2007 and played in just six games before announcing his retirement following the season.

2019 – K/P Kaare Vedvik

The Ravens groomed Vedvik, an undrafted kicker/punter out of Marshall (via Norway), and when he started out hot in the 2019 preseason, Baltimore dealt him to the Minnesota Vikings for what turned out to be a fifth-round pick. Vedvik didn't last long in Minnesota, but the Ravens used that draft pick to select defensive tackle Broderick Washington, who Baltimore signed to a contract extension this offseason.

2007 – RB Willis McGahee

The Ravens acquired McGahee from the Bills in March in exchange for two third-round picks and a seventh rounder. McGahee responded with his first Pro Bowl season, gaining 1,207 yards while averaging 5.4 yards per carry. That was the best of McGahee's four seasons with Baltimore, but he was a part of three playoff teams and scored 35 career touchdowns for the franchise.

2014 – C Jeremy Zuttah

In March of 2014, Baltimore acquired Zuttah from the Buccaneers in exchange for a fifth-round pick. He became the team's starting center for the next three seasons and made his only Pro Bowl in 2016 after starting all 16 games. In March of 2017, the Ravens traded Zuttah and a sixth-round pick to the 49ers in exchange for a sixth-round pick. He was released by the 49ers prior to the 2017 season and never played another game.

2013 LT Eugene Monroe

In October of 2013, the Ravens acquired Monroe from the Jaguars in exchange for fourth- and fifth-round picks. Monroe, who was 26 years old and a former first-round pick, started 11 games in 2013 but struggled with injuries the next two years after signing a five-year contract. Limited to 11 games in 2014 and just six games in 2015, Monroe was released in June of 2016 and retired a month later.

2020 – DE Yannick Ngakoue

Adding to their pass rush before the trade deadline, the Ravens acquired Ngakoue from the Vikings in exchange for a third-round pick and a conditional fifth rounder. Ngakoue had three sacks in nine games for Baltimore, including a two-sack performance in a victory over the Jaguars. His stay with the Ravens was short-lived, when he became a free agent after the season and signed with the Raiders.

1999 – QB Scott Mitchell

Looking for a starting quarterback, the Ravens acquired Mitchell from the Lions in exchange for third-round and fifth-round picks. Mitchell started just two games and struggled with one touchdown pass and four interceptions before being benched in favor of Stoney Case in Week 2. Tony Banks became the eventual starter that year, and Mitchell never played again before signing with the Bengals the following season.

2011 – WR Lee Evans

During training camp, the Ravens acquired Evans from the Bills for a fourth-round pick. Evans had spent seven seasons with Buffalo and was twice a 1,000-yard receiver. However, injuries limited Evans to just nine regular-season games with the Ravens with four catches for 74 yards. In the 2011 AFC Championship game at New England, Evans failed to hold onto a potential game-winning touchdown catch in the waning seconds. The Ravens lost 23-20 when Billy Cundiff missed a 32-yard field goal attempt with 15 seconds to play.
