These guys might not exactly be carrying a lunch pail to the stadium each week, but they did bring a blue-collar, working-man approach to the weekend's games. Take a look at all the nominees, then vote on your choice for the Hardest-Working Man for Week 15.
Antwan Barnes, San Diego Chargers
The Chargers -- despite a midseason six-game losing streak -- are shockingly still in the thick of the race for the AFC West crown, with their chances of the postseason getting a major boost from a thorough domination of the former AFC North leaders, Baltimore. Leading that throttling was the Chargers defense, which harassed Joe Flacco the entire game, forcing two interceptions and sacking the Ravens' quarterback seven times. Barnes led that charge into Baltimore's backfield, registering a career-high four sacks. Barnes' total is also the second-highest in Chargers history (defensive end Leslie O'Neal had five in a 1986 game against the Cowboys).
Tamba Hali, Kansas City Chiefs
The Chiefs made the Packers' run at perfection history, with the defense -- the unit coached all season by current interim coach Romeo Crennel -- shutting down one of the league's most prolific offenses in a 19-14 win. Hali was a big part of keeping Aaron Rodgers and crew out of the end zone. Hali spent much of the day in the Packers' backfield, harrassing Rodgers, and earning three sacks that helped spring the monumental upset.
Aaron Hernandez, New England Patriots
Hernandez set career highs with nine catches for 129 yards, including a touchdown, as the Patriots put a stop to Tebow Time and earned a playoff spot with a 41-23 win over the Broncos. The big day came with the Broncos keying on Rob Gronkowski, who's made a habit of having huge games of late.
Calvin Johnson, Detroit Lions
Johnson caught nine passes for 214 yards and two touchdowns, but it was his effort on the Lions' 98-yard winning drive that was most impressive. On the Lions' final drive for victory, Johnson had three catches for 75 yards and the winning touchdown. A fourth pass on the seven-play drive resulted in a pass-interference call on the Raiders and set up the 6-yard scoring strike. The victory put the Lions on the brink of their first playoff appearance since 1999.
Dan Orlovsky, Indianapolis Colts
One of the many faces of the Lions' 0-16 fiasco in 2008 was Orlovsky, and his run into the back of the end zone against the Vikings is one of that team's signature moments of infamy. Orlovsky made seven starts for the Lions in 2008, and it appeared his career would intersect with another unfortunate winless season. However, in his third start for the Colts, Orlovsky helped the Colts avoid 0-16. On the game's decisive play, and with Donald Brown appearing as if he might be tackled for a loss of yards, Orlovsky executed the block that sprung the running back free for an 80-yard jaunt for a score. For good measure, Orlovsky threw a TD pass as well as the Colts collected their first win of the season.
