SI.com's NFL personnel expert Michael Lombardi
evaluates the Titans' units.
Decisive year for Young; he has to become a passer.
Rookie Chris Johnson is potential playmaker; White is inside power.
There's not much here in the way of speed or depth.
Free-agent Crumpler must prove he can stay healthy.
Very good in both run blocking and pass protection.
Great talent; Haynesworth cannot be single-blocked.
Return of Fowler would boost the run defense.
Finnegan is good in coverage; looking for a big year from Griffin.
Bironas makes clutch kicks; coverage teams are solid.
