Back in my days covering the National Hockey League, "man games lost" were insightful stats we used frequently. The figures helped illustrate how injuries were impacting a team's season.

Man games lost aren't avidly tracked in the NFL. Rosters are more volatile than in the NHL, where fully guaranteed contracts generally cement a roster coming out of training camp.

NFL teams cut and sign players more frequently. Injured players can dress because there's one game a week, and they can be used situationally. In the NHL, you have to play offense and defense. There are no third-down specialists you can safely insert for a shift or two.

Football Outsiders managing editor Bill Barnwell has compiled a worthwhile chart for the NFL.

Better than man games lost, it's starter games lost.

The Indianapolis Colts led the NFL with 89. The Chicago Bears and Kansas City Chiefs were tied for fewest at 11.

In the AFC East, the Miami Dolphins had the most with 62, ranking seventh in the league. They were banged-up all along the offensive and defensive lines. Receiver Brian Hartline, cornerback Will Allen and rookie defensive end Jared Odrick went to injured reserve among a few others.

The New England Patriots were tied for 10th with 54 starter games lost. Tom Brady played through a foot fracture, but they most notably lost cornerback Leigh Bodden and offensive linemen Stephen Neal and Nick Kaczur.

The Buffalo Bills were tied for 21st with 42 starter games lost. That's a great development after what happened to them in 2009, when they finished with 21 players on injured reserve, including left tackle Demetrius Bell, right tackle Brad Butler, inside linebacker Kawika Mitchell, starting cornerbacks Leodis McKelvin and Terrence McGee and Pro Bowl safety Jairus Byrd.

The New York Jets lost starters 38 times, ranking 23rd in the league. Their biggest losses were nose tackle Kris Jenkins, safety Jim Leonhard and right tackle Damien Woody.

What do these numbers say, especially when four of the top five most injury-riddled teams (Colts, Green Bay Packers, Seattle Seahawks, Philadelphia Eagles) made the playoffs?

It means that depth (or playing in the NFC West) is imperative to surviving.

Barnwell offered to break down the chart by upper-body and lower-body injuries, but I haven't gotten that file yet.
