This is about more than replacing Michael Turner. LaDainian Tomlinson will be 29 when training camp opens and the Chargers need a youthful option incase L.T. starts to show his age. Johnson is a terrific receiver out of the backfield and a dynamic threat in space. He ran a mind-blowing 4.24-second 40-yard dash at the Combine, racing his way into the first round.
3. Jamar Adams, SS, Michigan
After releasing Marlon McCree at the onset of free agency, the Chargers are left with only two pure safeties on the roster. Adams enjoyed a monster senior season, tallying 92 tackles, 10 pass breakups and three interceptions. He has the size (6'2", 212 pounds) to play in the box and the instincts to patrol centerfield.
NT Marcus Harrison
Jamal Williams will be 32 next season and can't be depended on to play a full 16-game schedule. His backup, Brandon McKinney, is unspectacular and was inactive throughout the postseason. Harrison (6'3", 310 pounds) has the strength to anchor at the point of attack and knows how to shed blocks and locate the ball-carrier.
6. King Dunlap, OT, Auburn
After cutting Shane Olivea and Roman Oben over the last five months, the Bolts have no backup tackles on the roster. Although this position could be addressed earlier in the draft, GM A.J. Smith believes offensive linemen can be landed late. Dunlap, who played college ball with Marcus McNeill in 2005, has elite size (6'8", 310 pounds) and strength, although his consistency is a work in progress.
7. Jonathan Zenon, CB, LSU
The Chargers have an opening at cornerback after losing Drayton Florence in free agency. Paul Oliver will help fill the void, but more competition is needed to prevent a drop-off. Zenon lacks elite speed (4.56-second 40-yard dash) but compensates with athleticism and anticipation. He has a knack for making key plays, although he sometimes gambles too much and gets burned as a result.
