SI.com's NFL personnel expert Michael Lombardi
evaluates the Chargers' units.
QB B
Rivers appears to have recovered from his knee injury.
RB A
Tomlinson and what's behind him make this unit one of NFL's best.
WR B
Chambers upgrades them; so would Buster Davis's emergence.
TE A
Gates is a star; good blocker in Brandon Manumaleuna.
OL A
Tough and physical in all aspects; clears the way for Tomlinson.
DL A
Like the OL, tough and physical; and can rush the passer.
LB B
Speed and depth here make special teams so effective.
DB B-
Cromartie came through; a big year from Weddle needed.
ST A
Can cover and, with Darren Sproles, run the ball back.
