SI.com's NFL personnel expert Michael Lombardi
evaluates the Colts' units.
The whole game runs through Manning, and he makes it all work.
Addai has become a star; this unit finally has some depth.
A healthy Harrison makes No. 3 Anthony Gonzalez better.
Clark is a vital part of the offense, but there's no depth.
Well-coached unit; key will be Ugoh's consistency.
Play hard and fast; have to, with Freeney double-teamed.
Speedy, active unit that works Indy's scheme very well.
When healthy, Sanders is one of the league's top playmakers.
Vinatieri very reliable; not many chances for Smith to punt.
