This is a look at how all 55 players (includes two suspended ones) were originally acquired by the Baltimore Ravens, whether it was through the draft, as an undrafted rookie or a veteran free agent.

The number that jumps out is nine, the number Ravens players who first joined the team as undrafted rookies, which is more than the team's first-round picks. Of the 22 projected starters (when you include Courtney Upshaw as a starting linebacker over Elvis Dumervil), 16 are draft picks, four are free agents and two came to the Ravens via trade.

Here is how this year's Ravens were built ...

First round (6): Joe Flacco (QB), Terrell Suggs (LB), Haloti Ngata (DT), Jimmy Smith (CB), Matt Elam (SS), C.J. Mosley (LB). Note: All six are expected to start the season opener. Only two have reached the Pro Bowl (Ngata and Suggs), although Flacco was a Super Bowl Most Valuable Player and Smith could be the team's next Pro Bowl player.

Second round (6): Ray Rice (RB)*, Torrey Smith (WR), Kelechi Osemele (OT), Courtney Upshaw (LB), Arthur Brown (LB), Timmy Jernigan (DT). Note: Rice, Smith and Osemele have exceeded expectations. Upshaw has been a solid starter. Brown has been the biggest disappointment of this group. Jernigan should make an impact in the defensive line's rotation this year.

Third round (7): Marshal Yanda (G), Lardarius Webb (CB), Bernard Pierce (RB), Brandon Williams (DT), Jah Reid (OT), Crockett Gillmore (TE), Terrence Brooks (FS). Note: Four should start the season opener: Yanda, Webb, Pierce and Williams. Reid has never developed as a starter-quality lineman. Gillmore and Brooks should play as rookies.

Fourth round (4): Dennis Pitta (TE), Kyle Juszczyk (FB), Gino Gradkowski (C-G), Lorenzo Taliaferro (RB). Note: Pitta is the star of this group, although Juszczyk seems ready for a breakout season. Gradkowski was replaced after a disastrous one year as as a starter. Taliaferro led the NFL in rushing this preseason as a rookie.

Fifth round (5): Rick Wagner (OT), Pernell McPhee (LB), Chykie Brown (CB), Asa Jackson (CB), John Urschel (G). Note: Wagner is the only starter of the current fifth-round picks on the team. McPhee will play a big role as a rusher on passing downs. Jackson beat out Brown to be the team's No. 3 corner. Urschel is a reserve interior lineman.

Sixth round (2): Tyrod Taylor (QB), Sam Koch (P). Note: Koch is in his eighth season as the Ravens' punter. The only players remaining from the 2006 draft are Koch and Ngata, who was the first-rounder that year. Taylor is in his fourth season as the Ravens' backup quarterback.

Seventh round (2): DeAngelo Tyson (DL), Michael Campanaro (WR). Note: Over the past four drafts, the Ravens have picked five players in the seventh round. Tyson and Campanaro are the only ones who made the cut. Running back Anthony Allen, wide receiver Aaron Mellette and cornerback Marc Anthony were all gone before this year's training camp.

Undrafted (9): Justin Tucker (K), Marlon Brown (WR), Deonte Thompson (WR), Morgan Cox (LS), Josh Bynes (LB), Albert McCellan (LB), Brynden Trawick (S), James Hurst (OT), Zachary Orr (LB). Note: Tucker and Brown were arguably the top rookies for the Ravens in each of the past two seasons. Bynes made the last tackle in the Super Bowl victory. Cox is in his fifth season as the long snapper, and McClellan led the Ravens in special teams tackles last season.

Free agents (12): Steve Smith (WR, Panthers), Daryl Smith (LB, Jaguars), Jacoby Jones (WR, Texans), Elvis Dumervil (LB, Broncos), Chris Canty (DE, Giants), Owen Daniels (TE, Texans), Darian Stewart (FS, Rams), Kamar Aiken (WR, Patriots), Justin Forsett (RB, Jaguars), Jeromy Miles (S, Bengals), Anthony Levine (S, Packers), Will Hill (S, Giants).* Note: Four starters from this group: Steve Smith, Daryl Smith, Canty and Stewart. Jones is the team's No. 3 receiver and an explosive returner. Aiken, Miles and Levine are key special-teams players.

Trade (2): Eugene Monroe (OT, Jaguars), Jeremy Zuttah (C, Buccaneers). Note: The Ravens traded a total of three draft picks for two starters on this year's offensive line.

*-Rice and Hill are on the suspended list.
