Question: The Dark Side: Secrets of the Sports Dopers was a documentary that accused the Green Bay Packers player of what position of using PEDs?

Context paragraphs:
Joe Laws: Joe Roy Laws (June 16, 1911 – August 22, 1979) was an American football player.  He played his entire career with the Green Bay Packers, winning three World Championships, and was inducted into the Green Bay Packers Hall of Fame in 1972.  Prior to joining the Packers, Laws attended the University of Iowa where he was a member of Sigma Pi fraternity.  While at Iowa he was named All-Big Ten quarterback and the Big Ten Most Valuable Player in 1933.  On December 17, 1944 Joe Laws set an NFL postseason record (since broken), by intercepting 3 passes in the Packers' 14-7 victory over the Giants in the league title game.

Packers Radio Network: The Packers Radio Network is a broadcast radio network and the official radio broadcaster of the Green Bay Packers football team.  The network's flagship is the E. W. Scripps Company's WTMJ in Milwaukee, Wisconsin, which has broadcast the games since November 24, 1929, and was the former flagship station of Journal Communications until Scripps and Journal completed their broadcast merger and publishing spin-off on April 1, 2015.  This is one of the few arrangements where a team's flagship radio station is not based in their home market and the local station serves as a network affiliate only, as WTMJ's signal to Green Bay and most of Wisconsin's population centers is city-grade; the rights for Packers games in the Green Bay area have bounced between Midwest Communications and Cumulus Media throughout the last few years, while stations carrying the games owned by Woodward Communications which nominally serve the Fox Cities exclusively have equally heavy listenership in Green Bay.

List of Green Bay Packers stadiums: The Green Bay Packers have played home games in eight stadiums since their establishment as a professional football team in 1919.  Their first home was Hagemeister Park, where they played from 1919 to 1922, including their first two seasons in the National Football League (NFL).  Hagemeister Park was a park owned by the Hagemeister brewery; during games ropes were set-up around the field and attendees either walked up or parked their cars nearby and used them for seats.  After the first season, a small grandstand was built and the field was fenced off.  Green Bay East High School was built at the location of Hagemeister Park in 1922, which forced the Packers to move to Bellevue Park, a small minor league baseball stadium that seated 5,000.  They only played for two seasons at Bellevue Park before moving to City Stadium in 1925.  Although City Stadium was the Packers' official home field, in 1933 they began to play part of their home schedule in Milwaukee to attract more fans and revenue.  After hosting one game at Borchert Field in 1933, the Packers played two or three home games each year in Milwaukee, at Wisconsin State Fair Park from 1934 to 1951 and at Marquette Stadium in 1952.  The games were moved to Milwaukee County Stadium after it opened in 1953 and continued through 1994, after which the Packers moved back to Green Bay permanently.

Green Bay Packers Hall of Fame: The Green Bay Packers Hall of Fame was the first hall of fame built to honor a single professional American football team.  William L. Brault, a Green Bay restaurateur and Packers fan, founded the Hall of Fame in 1966.  According to Brault, he got the idea after visitors to Green Bay would repeatedly ask about the Packers' storied history.  Sensing opportunity, Brault went to Packers head coach Vince Lombardi, suggesting a "Hall of Fame" should be made to educate tourists about the Packers and their history.  Lombardi gave Brault his approval, and according to Brault, as he left, Lombardi called out to him, "Don't screw it up!"

Green Bay Packers Fan Hall of Fame: The Green Bay Packers Fan Hall of Fame (capitalized by the organization as the Green Bay Packers FAN Hall of Fame) was the first hall of fame built to honor fans of a professional football team.  It was established by the Green Bay Packers and the Green Bay Packers Hall of Fame in 1998.  Fans may nominate themselves or others for inductions by submitting an essay of 500 words or less, accompanied by a photo or a two-minute video, explaining why they or another person are the ultimate Packers fan and deserve recognition.  Ten finalists are chosen by a selection committee composed of members of the Packer Hall of Fame board and members of the Green Bay Packers' front office, and are profiled in the Milwaukee Journal Sentinel, as well as on the Packers' website.  Fans are then given an opportunity to vote on the 10 finalists whose stories were profiled.

Clay Matthews III: William Clay Matthews III (born May 14, 1986) is an American football outside linebacker for the Green Bay Packers of the National Football League (NFL).  After attending Agoura High School in Agoura Hills, California, Matthews was a walk-on student athlete at the University of Southern California for the USC Trojans football team under head coach Pete Carroll.  At USC, Matthews was a standout special teams player, winning three consecutive Special Teams Player of the Year awards from 2006 to 2008; he also played reserve outside linebacker.

2013 Green Bay Packers season: The Green Bay Packers season was the franchise's 94th season in the National Football League, the 95th overall and the eighth under head coach Mike McCarthy.  The Packers came into the 2013 season looking to win the NFC North for the 3rd year in a row.  They were coming off a 45-31 loss to the San Francisco 49ers in the NFC Divisional Playoffs.  The Packers started the 2013 season with a rematch with the 49ers in San Francisco.  They lost the game 34-28.  After winning their home opener against the Redskins, they lost 34-30 in Cincinnati to the Bengals after they had a 30-14 lead in the 3rd quarter.  After the loss, the Packers would win 4 games in a row to sit at 5-2 before losing a Monday Night game at home to the Bears 27-20.  In that game, the Packers would lose star quarterback Aaron Rodgers to a broken collarbone in the 1st quarter.  He would be replaced by Scott Tolzien and sometimes Matt Flynn.  In week 12, the Packers tied the Vikings 26-26.  It was Green Bay's first tie since 1987.  The Packers would lose the next game 40-10 to the Lions on Thanksgiving to sit at 5-6-1, and looking like being on the verge of missing the postseason for the first time since 2008.  The Packers would then beat the Falcons 22-21 to even their record at 6-6-1.  The following week, the Packers defeated the Dallas Cowboys 37-36 in Dallas after they had trailed 26-3 at halftime.  The comeback was the largest in franchise history.  The Packers would then lose a shootout with the Pittsburgh Steelers 38-31 at home to sit at 7-7-1, the first meeting between the teams since Super Bowl XLV.  The next week, the Packers defeated the Chicago Bears 33-28 at Soldier Field to clinch the NFC North in a game in which the winner would've clinched the division.  The game was famously well known for a touchdown catch made by Randall Cobb from Aaron Rodgers with less than a minute remaining to seal the win.  The play came on a 4th and 8 situation in which Cobb was wide open near the endzone.  The Packers entered the playoffs as the 4 seed in the NFC.  In the wild card game, they lost 23-20 in a rematch with the 49ers on a Phil Dawson field goal as time expired.  The game was one of the coldest in NFL playoff history, with a final temperature of 5 °F (-15 °C)

Packers Pro Shop: The Packers Pro Shop has been the official retail store of the National Football League's Green Bay Packers since 1989.

Locker Room (WFRV-TV): "Locker Room" (formerly "Larry McCarren's Locker Room") is a live talk show hosted by WFRV-TV sports director Burke Griffin and former Green Bay Packer Ahman Green.  It used to be hosted by former WFRV sports director and former Green Bay Packer Larry McCarren, who is now the sports director at WGBA-TV.  Every week during football season, a Packers player visits the show.  That player is then interviewed, and then that player must teach one selected member of the audience how to do a task to earn their autograph; the concept is called "Earn Your Autograph."  Also, there is a segment on the show called "Chalk Talk," where certain plays are selected in the previous Packer game and are talked through.
