SI.com's NFL personnel expert Michael Lombardi
evaluates the Patriots' units.
QB A
Best in the business—do-it-all Brady makes his teammates better.
RB B
LaMont Jordan could be the short-yardage/third-down weapon.
WR A
With Moss and Welker, everyone else draws single coverage.
TE B
Keys are Watson's heath, finding a reliable blocker.
OL B
Played well until Super Bowl; Light's health is key.
DL A
Big, physical; cannot be moved off the line of scrimmage.
LB B
Rookie Jerod Mayo's speed, quickness will enhance front seven.
DB B-
Disciplined and well-coached; have added youth and speed.
