As camps around the league open this week, the stars will deservedly get the bulk of the attention.

However, the NFL is a war of attrition and medical issues can quickly mount. Roster depth is a critical factor to most team's success. Granted if your favorite team has a few superstars and they avoid injury, then depth isn't as big of an issue. Although for most squads, depth is a major component for winning and losing.

Each year I examine every depth chart right before training camp commences, looking for the teams with the best depth. A year ago, I declared the Washington Redskins as the team with the most quality depth heading into training camp. Injuries to the offensive line immediately challenged their depth and the club responded with a playoff performance.

While the Redskins are in the top five this year, there are other teams with excellent depth that didn't make the cut and, in some cases, had better people at certain positions. I really like the San Diego Chargers roster, but the loss of Michael Turner raises some questions about the backup running back situation as does the loss of nickel corner Drayton Florence.

Evaluating depth on a roster starts at quarterback. Ask yourself, how good is the backup? Can he stay healthy? Can he perform with limited reps in practice? If he has to play for a month, can he go 3-1? When quarterback questions are answered, more than half of the 32 get eliminated. The Arizona Cardinals, Houston Texans, Minnesota Vikings, New Orleans Saints, Philadelphia Eagles, Pittsburgh Steelers, San Diego Chargers, Saint Louis Rams, Tampa Bay Buccaneers, Tennessee Titans, Washington Redskins, Jacksonville Jaguars and Green Bay Packers, if they get Brett Favre back, remain alive.

Chester Taylor rushed for 1,216 yards in 2006, but took on a smaller role with the Vikings as Adrian Peterson emerged last year.

From this group, the second question is which teams have a reserve running back capable of rushing for 1,000 yards if called up upon to replace the starting tailback? Now the list gets reduced to the Vikings, Steelers, Buccaneers, Redskins and Jaguars. The Saints, Titans, Texans and Eagles are also possibilities.

Take these nine teams and examine the offensive line. Who has a swing tackle for the left or right side? Which teams also have a backup interior lineman who can handle playing guard or center? The Vikings, Steelers, Buccaneers, Redskins, Jaguars, Texans and Eagles can answer in the affirmative.

Of the seven remaining teams, only the Texans are without a third wide receiver capable of starting for other teams.
