MEQUON, Wis. -- The rosters I maintain for NFL teams will need updating once teams settle on starting lineups for the upcoming season.

But based on projected lineups, the Rams' defensive starters would average 29.0 years old, fifth-oldest in the league, with 32-year-old Chris Draft starting at strong-side linebacker. The average falls to 28.1 years old, 16th-oldest in the league, if 22-year-old Quinton Culberson beats out Draft for the job. Defensive linemen La'Roi Glover, 34, and Leonard Little, 33, pump up that average.

Glover remains a productive player if the Rams can limit his snaps. The team thinks Little will reemerge as a pass-rush threat this season. If he does, the Rams are a much different team defensively.

Note: Calculating exact ages (without rounding down to the nearest year) is the key to producing accurate averages.

Also at linebacker: The Rams waived rookie free agent Vince Hall, linebacker from Virginia Tech. They signed rookie free agent Marcus Riley, linebacker from Fresno State. Riley is wearing No. 54.
