There's only so much stretching, lifting and training a player can do to stay healthy. Sometimes it just comes down to having a little luck.

Sean Lee mentioned that four-letter word last week when asked about completing his first fully healthy season in seven years with the club.

"The game plan the coaches and the trainers have put together has been big," the All-Pro linebacker said. "At the same point, I think I've kind of had a little bit of luck. So I think it's been a combination of a lot of things, but I've done a lot of work to try to improve and get away from those injuries."

Lee isn't alone in the luck department. Dallas enters the playoffs as the healthiest of the eight remaining teams.

Sure, the Cowboys have had starters miss time with injuries. Tony Romo, Dez Bryant, Tyron Smith, La'el Collins, DeMarcus Lawrence, Tyrone Crawford, Morris Claiborne, Orlando Scandrick and Barry Church have missed at least two games each. But Collins is the only one who hasn't healed up. Everyone else is expected to play in Sunday's divisional-round game.

The argument can be made that the Cowboys are the healthiest they've been all season.

"I don't think there's any question," Cowboys executive vice president Stephen Jones said recently on 105.3 The Fan's Ben and Skin show [KRLD-FM]. "We were actually talking about that, to think pretty much when you look at this football team that we may have access to almost everybody.

"You have to have some of that good fortune in terms of injuries."

The other seven remaining playoff teams haven't been as fortunate.

The Green Bay Packers, Dallas' divisional-round opponent, lost starting running back Eddie Lacy and starting cornerback Sam Shields earlier in the season. They'll also likely be without leading receiver Jordy Nelson, who took a helmet to the ribs in the second quarter of their wild-card game.

Nelson had only one catch for 13 yards, and the Packers outscored the Giants 38-10 without him. But it's a huge advantage for the Cowboys if they can avoid a player who had 1,257 receiving yards and 14 touchdowns this season.

Atlanta and Seattle can relate. The Seahawks are playing this postseason without All-Pro safety Earl Thomas and wide receiver/returner Tyler Lockett. The Falcons are missing cornerback Desmond Trufant, linebacker Sean Weatherspoon and tight end Jacob Tamme.

Over in the AFC, star players Rob Gronkowski and J.J. Watt won't be on the field when New England hosts Houston. Defensive end Cameron Heyward won't be trying to tackle running back Jamaal Charles when Pittsburgh travels to Kansas City. All four had their seasons cut short because of injury.

The Cowboys' two biggest losses: Collins and tight end Geoff Swaim.

Dallas, of course, isn't feeling sorry for anyone. Injuries to Romo and Bryant are the biggest reason for last year's 4-12 disaster.

When they fell short against the Packers in the divisional round in 2014, Lee was recovering from a knee injury.

Maybe a healthy Lee makes the difference this time around.

"I remember watching [Aaron] Rodgers take it down the field against us two years ago and wishing we had Sean Lee out there," Cowboys owner Jerry Jones said. "He's a difference maker. It's really an enhancement to our chances here in the playoffs to have a healthy Sean Lee out there."
