Last year the duo of Joel Dreessen (+4.0) and Tamme helped count the Broncos' offense among the best in the league, but the offseason addition of Wes Welker and emergence of Julius Thomas have left both players on the bench this season. That depth might be needed depending on how long Welker is out with yet another concussion. Kevin Vickerson landing on injured reserve has really hurt the interior of the Broncos' defense, as first-round rookie Sylvester Williams (-6.8) hasn't made much of an impact in his limited playing time.
Backups grade: 28.0 | Deepest position group: Defensive tackle
Shallowest: Halfback | Best non-starter: S George Wilson (+13.2)
The Titans have great depth at some positions, but are lacking in other areas. Wilson, a free-agent addition, has given Tennessee one of the best backup safeties in the league. In Tennessee, there just aren't enough snaps on the defensive line to go around with Karl Klug (+25.9) and Mike Martin (+17.0) both excelling at generating an interior pass rush the past two years. On offense, both Craig Stevens (+1.9) and Taylor Thompson (+7.1) are decent run-blockers at tight end.
Backups grade: 27.6 | Deepest position group: Defensive back
Shallowest: Tight end | Best non-starter: NT Dan Williams (+14.6)
The Cardinals are a team that brought in much of their quality depth in the offseason. Sixth-round rookie Andre Ellington (+9.2) has already made an impact as the team's backup running back, while undrafted rookie wide receiver Jaron Brown (+1.8) has played well in his limited opportunities. Marcus Benard (+5.0) and Javier Arenas (+4.9) were added to the roster, but haven't been needed recently due to the depth. Tight end and offensive line are both still problem areas, preventing the Cardinals from ranking higher on this list.
10. Atlanta Falcons
Backups grade: 27.5 | Deepest position group: Halfback
Shallowest: Linebacker | Best non-starter: HB Jacquizz Rodgers (+14.8)
The Falcons' depth is about quality and not quantity, with that quality focused on the offensive skill players. Year after year, Rodgers and Jason Snelling (+3.2) continue to be two of the best backup receiving backs in the league. On defense, the most notable player is fourth-round rookie defensive end Malliciah Goodman (+2.9), who should see his playing time increase this last month of the season. Part of Atlanta's downfall this season has been the lack of depth at linebacker as well as wide receiver.
Backups grade: 25.7 | Deepest position group: Tight end
Shallowest: Defensive back | Best non-starter: OLB Brandon Graham (+43.7)
