Mack is a two-time Pro Bowler and would be a great addition to the Ravens' line, which Ozzie Newsome said he wants to bulk up. Mack was given the transition tag, however, so the Browns can match any offer made to him.

Sims is coming off a breakout year in which he started all 16 games and made 54 tackles and two sacks. He's a beefy (6-foot-2, 310 pounds) former third-round pick of the Bengals. Sims would help offset the loss of Art Jones and perhaps Terrence Cody as a run stuffer.

Clemons isn't flashy, but he's a solid option in the back end. He's officially listed as a strong safety, but has strong coverage skills. Clemons had eight pass deflections and one interception last season. He would likely take over at free safety, allowing Matt Elam to move to strong safety.

Penn was once considered one of the best tackles in the NFL. He was a Pro Bowler in 2010. Penn was released by the Tampa Bay Buccaneers because he had a large cap number heading into 2014. Penn has mostly played left tackle, but has experience on the right side as well and would fit there in Baltimore.

Joseph and Penn made a formidable 1-2 punch for years. Joseph went to the Pro Bowl in 2008 and 2001. The Bucs reportedly tried to trade the 30-year-old veteran but ended up cutting him for salary reasons. Joseph could be a solution if the Ravens moved left guard Kelechi Osemele to right tackle.

DeCoud has missed only two starts in Atlanta the past five years. He went to the Pro Bowl in 2012 after grabbing six interceptions, but took a step back last season. He had only two pass deflections and no interceptions. DeCoud was then cut by the Falcons. He would be a high coverage safety in Baltimore with playmaking potential.

The Ravens want to diversify their running back corps and the 6-foot, 250-pound Blount would do just that. He rumbled for 772 yards last year in New England, including 189 yards in the regular-season finale in Buffalo and 166 yards against Indianapolis in the playoffs. Blount could help split carries between Ray Rice and Bernard Pierce, and be used as a short-yardage or goal-line option.

Williams is a six-time Pro Bowler who started 15 games for the Minnesota Vikings at age 33 last season. He made 29 tackles, 3.5 sacks and one interception.

De La Puente is one of the best centers still available. He was out of the league for two years in 2009 and 2010, but started all 16 games the past two years in New Orleans. If signed, De La Puente would likely be the leading option at center, but would compete with Gino Gradkowski.

Daniels is a favorite of Ravens Offensive Coordinator Gary Kubiak. The two were together for eight years in Houston when Daniels had his best years and went to two Pro Bowls (2008, 2012). Daniels and Dennis Pitta would make an excellent receiving duo, as both can split out wide.

Britt looked like a monster in his first couple years in the league, but has trailed off dramatically. He started just three games last year and caught 11 passes for 96 yards. There are also character red flags. The Ravens could still welcome a big-bodied, less expensive option on the outside.

Carrington, a third-round pick in 2010, never really panned out in Buffalo. He played just three games last year due to a quadriceps injury. But he's scheme versatile and huge at 6-foot-5, 301 pounds. Carrington would help fill in for the departed Jones.
