Jah Reid's untimely strained right calf injury has prevented him from making a bid for playing time after being projected by the Ravens as a potential starting guard during the offseason.

Gritty veteran Tony Wragge could figure in as a valuable swing player as an interior lineman.

Ramon Harewood's health continues to be unreliable, the book on him since being drafted in the sixth round out of Morehouse.

Justin Boren is highly regarded for his toughness, but is more of an in-line fighter than anything else, as he doesn't get to the second level often.

Undrafted tackle Jack Cornell is a technician, an uncommonly mature rookie chasing a roster spot who's done enough for general manager Ozzie Newsome to single him out to owner Steve Bisciotti.

DEFENSIVE LINE

This shapes up as a fairly deep group. That is, when everyone's healthy.

Pernell McPhee, the top pass rusher of the unit, is working his way back from a knee injury that required arthroscopic surgery in the spring.

Starting left defensive end Arthur Jones was having a nice camp until a strained hip flexor sat him down.

Massive nose guard Terrence Cody is a huge anchor in the middle of the defensive line. By upgrading his conditioning and dropping a significant amount of body fat since his rookie year, Cody has better energy to occupy blockers, push the pocket and occasionally shoot gaps.

Pro Bowl defensive tackle Haloti Ngata is significantly heavier than he was a year ago when he played at roughly 335 pounds. He still moves uncannily well for a player with so much bulk. Ngata's desire to bulk up stemmed from wearing down last season, but he pulled his hamstring when he took the conditioning test for the first time.

Ngata is still playing his way into shape after returning to full-time duty Monday. The Ravens are looking for a major return on their $61 million investment in Ngata, one of the most disruptive interior forces inthe game.

It's very competitive for reps among Ryan McBean, Ma'ake Kemoeatu, DeAngelo Tyson and Bryan Hall. McBean could give the front seven a lift when he returns from a pending three-game suspension for violating the NFL's performance enhancing drug policy.

Kemoeatu is trying to revive a career nearly derailed by injuries and weight issues.

Hall is an improving young player.

Imposing rookie nose guard Ishmaa'ily Kitchen (6-1, 332 pounds) is a name worth remembering.

LINEBACKER

Middle linebacker Ray Lewis is trying to defy his age and remain a three-down player by losing a lot of weight this offseason. He's not much bigger than strong safety Bernard Pollard, but he does look quick. Listed at 240 pounds, the two-time NFL Defensive Player of the Year appears closer to 230pounds.

Lewis is following a trend of older linebackers who kept getting lighter in the twilight of  their
careers, including former Pittsburgh Steelers middle linebacker James Farrior. The true test will come against bigger backs in the regular season. For now, Lewis' experiment of preserving his status as a full-time player appears to be working for him.
