The Baltimore Ravens open training camp July 28 at the Under Armour Performance Center in Owings Mills, Maryland. Here's a starting lineup projection.

Offense

Quarterback (Joe Flacco): Flacco is coming off season-ending knee surgery, which stopped his streak of 122 regular-season games played, the fifth-longest by a quarterback in NFL history.

Running back (Justin Forsett): Forsett needs to fight off Buck Allen, Kenneth Dixon, Terrance West and Lorenzo Taliaferro to keep his starting job after gaining 1,907 yards rushing since 2014, eighth-most in the NFL in that span.

Fullback (Kyle Juzczyk): He led all NFL fullbacks with career highs in receptions (31), receiving yards (321) and touchdown catches (four) last season.

Wide receiver (Steve Smith Sr.): He returns after delaying retirement for another season and sits 11th on the NFL's all-time leading receiver list with 13,932 yards.

Wide receiver (Mike Wallace): His 44 catches and 21 touchdown receptions on passes that traveled at least 25 yards in the air rank second only to DeSean Jackson in the past seven seasons.

Tight end (Benjamin Watson): Watson ranked sixth in the league last season with five red-zone touchdowns, two more than the combined total for the Ravens' tight ends last season.

Left tackle (Ronnie Stanley): The No. 6 overall pick, he is the Ravens' highest draft pick since running back Jamal Lewis went No. 5 overall 16 years ago.

Left guard (John Urschel): The leading candidate to replace Kelechi Osemele, Urschel will battle Ryan Jensen and rookie Alex Lewis for the starting spot.

Center (Jeremy Zuttah): He graded out as Pro Football Focus' No. 8 center, excelling in both run blocking and pass protection, before missing the final seven games with a partially torn pectoral muscle.

Right guard (Marshal Yanda): Selected to the past five Pro Bowls, a streak that trails only two offensive linemen: Cleveland's Joe Thomas and New Orleans' Jahri Evans.

Right tackle (Rick Wagner): A former fifth-round pick, he is entering a contract year after starting 31 of the past 32 games.

Defense

Defensive tackle (Timmy Jernigan): He's coming off a season in which he set a career high in tackles (37), and an offseason that included a controversy with Warren Sapp over a jersey number change.

Nose tackle (Brandon Williams): Williams is one of four defensive tackles to record at least 30 solo tackles, two sacks and two passes defensed last season. Ndamukong Suh, Jurrell Casey and Kawann Short are the others.

Defensive end (Lawrence Guy): Guy held his own while replacing Chris Canty for six games last season and will compete against Brent Urban and Bronson Kaufusi for the starting job.

Outside linebacker (Terrell Suggs): Suggs recorded the ninth-most sacks (49) from 2010 to 2014 before suffering a torn Achilles in last year's season opener.

Inside linebacker (C.J. Mosley): Mosley is the only defender in the league to make at least 225 tackles, five sacks and two interceptions the past two seasons.

Inside linebacker (Zachary Orr): Orr is the top candidate to replace leading tackler Daryl Smith, but must fend off Kamalei Correa, Albert McClellan and Arthur Brown.

Outside linebacker (Elvis Dumervil): He has the most multiple-sack games (31) of any active player since 2006, and his 96 sacks are the second-most in that span.

Cornerback (Jimmy Smith): Smith is one of seven defenders who had at least 50 tackles, three interceptions, 10 passes defensed and one sack last season.

Safety (Eric Weddle): Weddle is just the second free agent from another team to receive more than $4 million in guaranteed money from the Ravens since 2010; Dumervil was the other.

Safety (Lardarius Webb): Webb is making a switch from cornerback to safety in a season when his $5.5 million base salary is the highest on the team.

Cornerback (Shareece Wright): Wright allowed 132 yards passing in his first game with the Ravens and gave up just 256 yards passing in his last 10, according to Pro Football Focus.

Special teams

Kicker (Justin Tucker): Tucker had a career-worst seven missed field goal attempts last season but made 12 of his last 13 attempts (92.3 percent).

Punter (Sam Koch): Koch earned his first Pro Bowl invitation after posting the NFL's second-best net average (42.9 yards). He limited returners to a franchise-record 5.0-yard punt return average.

Long snapper (Morgan Cox): Cox returned from a season-ending knee injury in 2014 and put together his first Pro Bowl season.

Returner (Keenan Reynolds): Reynolds is making a transition from a triple-option quarterback at Navy, where he scored the most touchdowns in NCAA history (88).
