NFL Depth Chart Rankings

— -- It seems like this NFL season more than ever, teams have experienced serious injuries that have weakened their rosters, which means the role of backups is more important than it's ever been. Just in this last week we saw Rob Gronkowski and Tyrann Mathieu, among others, land on injured reserve. And we probably aren't done seeing major injuries hit as the wear and tear of the season takes its toll on players.

The question then becomes: Which team is best suited if one of its starters was to get hurt? To answer that question, we present to you the NFL Depth Chart Rankings, which evaluate the depth of talent on every NFL roster heading down the home stretch of the season and into the playoffs.

First, a few details on how the rankings were constructed. We took the ideal lineup for each team based on their current healthy players, as well as the players likely to return this season, and ranked the backups for each team. These rankings were created using overall PFF Grades of the backup players over their last 1,000 snaps and focused on the strength of the quality backups rather than the inexperienced backups. Each player's grade was capped at plus-5.0 so that an individual backup would not overly influence the team's rating.

The quarterback position was also ignored, since nearly every team would see their Super Bowl dreams shattered if their starting quarterback was hurt. The focus of these rankings is to illustrate how much depth each team features -- and whether they can survive -- in the event starters are lost due to injury.
