Problem: With the rapid growth and consolidation of large railroad systems after 1870, union organizations sprang up, covering the entire nation. By 1901, 17 major railway brotherhoods were in operation; they generally worked amicably with management, which recognized their usefulness. Key unions included the Brotherhood of Locomotive Engineers , Brotherhood of Maintenance of Way Division , the Order of Railway Conductors, the Brotherhood of Locomotive Firemen, and the Brotherhood of Railroad Trainmen. Their main goal was building insurance and medical packages for their members, and negotiating bureaucratic work rules that favored their membership, such as seniority and grievance procedures. They were not members of the AFL, and fought off more radical rivals such as the Knights of Labor in the 1880s and the American Railroad Union in the 1890s. They consolidated their power in 1916, after threatening a national strike, by securing the Adamson Act, a federal law that provided 10 hours pay for an eight-hour day. At the end of World War I they promoted nationalization of the railroads, and conducted a national strike in 1919. Both programs failed, and the brotherhoods were largely stagnant in the 1920s. They generally were independent politically, but supported the third party campaign of Robert M. La Follette Sr. in 1924.

Problem: Coming off their dominating divisional road win over the Raiders, the Broncos played their Week 2 home opener against the AFC West foe, the San Diego Chargers. In the first quarter, Denver was first out of the gate as FB Michael Pittman got a 1-yard TD run. The Chargers would respond with kicker Nate Kaeding getting a 34-yard field goal. In the second quarter, Denver replied with QB Jay Cutler completing a 3-yard and a 14-yard TD pass to TE Tony Scheffler. San Diego would immediately respond with RB Darren Sproles returning the kickoff 103 yards for a touchdown, yet the Broncos replied with rookie kicker Matt Prater getting a 52-yard field goal. The Chargers would strike as their lead as QB Philip Rivers completed a 48-yard TD pass to WR Chris Chambers, yet Denver retaliated with Cutler completing a 6-yard TD pass to WR Brandon Marshall. In the third quarter, San Diego started to rally as Rivers completed a 15-yard TD pass to Chambers, and Kaeding kicked a 21-yard field goal. In the fourth quarter, the Chargers took the lead with Kaeding's 28-yard field goal and Rivers' 66-yard TD pass to Sproles. Fortunately, the Broncos responded with a 12-play, 80-yard drive (which included a controversial officiating call that turned a Cutler fumble into an incomplete pass) that was capped off with Cutler's 4-yard TD pass to rookie WR Eddie Royal, followed by Cutler's successful 2-point conversion pass to Royal. Brandon Marshall's 18 receptions would become a single-game franchise record and tie for 2nd most in league history.

Problem: Tampa Bay traveled west to San Francisco for the third time in five seasons. Tampa Bay lost their eighth consecutive meeting at Monster Park, dating to 1980. This game was originally scheduled for 8:15p.m. on NBC's Sunday Night Football, but on December 10, in accordance with flex-scheduling, the game was moved to the afternoon. Having already clinched a playoff berth, Tampa Bay rested most of their starters in the second half. Despite a late rally, the Buccaneers fell two points short of victory. Tampa Bay controlled most of the first half, capping off their first two drives of the first quarter with field goals by Matt Bryant. On the first play of the second quarter, Shaun Hill connected with Darrell Jackson on a 21-yard touchdown. San Francisco punted on their next drive, and Micheal Spurlock fielded the ball at the 19-yard line. He was tackled and fumbled, while the 49ers recovered. After an instant replay challenge, it was determined that Spurlock was down by contact, and Tampa Bay maintained possession. The drive fizzled though, and ended with a punt. Late in the fourth quarter, Barrett Ruud recovered a 49ers fumble, setting the Buccaneers up on the San Francisco 36-yard line. Four plays later, Jerramy Stevens caught a touchdown pass from Jeff Garcia. Tampa Bay took a 13-7 lead into halftime. On the second-half kickoff, San Francisco recovered a surprise onside kick. The drive came up empty, as they were forced to punt. On Tampa Bay's next possession, however, Luke McCown (who had taken over for the benched Garcia) fumbled and the 49ers recovered at the 14-yard line. In four plays, San Francisco scored a touchdown. Early in the fourth quarter, Nate Clements intercepted a McCown pass, and led to another 49ers touchdown. The 49ers led 21-13, but Tampa Bay still kept hopes alive for a rally. With less than six minutes left in the game, the Buccaneers drove to the 49ers 25-yard line. On 4th down and 6, McCown threw to Michael Clayton for an apparent one-handed touchdown catch, but the ball fell incomplete, and the drive turned over on downs. Tampa Bay managed one final chance to tie the score. Inside the two-minute warning, Tampa Bay drove to the 49ers 24-yard line. McCown rolled out wide to his right, and connected with Stevens for a 24-yard touchdown. McCown then attempted a game-tying two-point conversion. Michael Clayton caught the pass, but one of his feet touched out-of-bounds in the back of the endzone, sealing the game for San Francisco.
