Before the season, the Portsmouth Spartans moved to Detroit, Michigan and were renamed the Detroit Lions. The Cincinnati Reds lost their first eight games, then were suspended for not paying league dues. The St. Louis Gunners, an independent team,  purchased the Cincinnati Reds franchise for $20,000.00 and played the final three games on the Reds schedule. Six of the Reds players joined the team for the final two games. The team was headquartered at the St. Louis National Guard Armory, which accounts for its nickname the "Gunners".  However, it would be the only season for the Gunners, as they would disband after the 1934 season.  The Pittsburgh Pirates were in their second season, and would eventually be known as the Pittsburgh Steelers, beginning in 1940. The 1934 season would be dominated by the Chicago Bears (13-0-0) and the Detroit Lions (10-3-0). The eventual NFL Champion, the New York Giants, would finish the season with an unimpressive 8-5-0 record. The Giants would win the Eastern Division by one game over the 7-6-0 Green Bay Packers. The Bears would win the Western Division by three games over the Detroit Lions.  This would set up the NFL Championship Game between the Chicago Bears and the New York Giants.  The 1934 NFL Championship Game, also known as The Sneakers Game, was played at the Polo Grounds in New York City on December 9, 1934. With a
remarkable fourth quarter, the New York Giants defeated the Chicago Bears 30–13. The defending champion Bears entered the game undefeated at 13–0, with an 18-game winning streak. The Giants (8–5) won consecutive division titles, but had lost their previous game at Philadelphia. A freezing rain the night before the game froze the Polo Grounds field. After Ray Flaherty, a Giants end, made a remark to Giants' head coach Steve Owen suggesting that sneakers would provide better footing on the frozen playing surface, Owen sent Abe Cohen to Manhattan College to get some sneakers. There, Brother Jasper, the athletic director (and the later namesake of the Manhattan Jaspers) emptied the
lockers of the school's basketball team. Cohen arrived in the third quarter with nine pairs of basketball sneakers from the college. The Bears led 10–3 at the half when the Giants switched to the basketball sneakers. A Chicago field goal was the only score in the third quarter, extending the lead to ten points. Early in the fourth, Giants quarterback Ed Danowski threw a touchdown pass to Ike Frankian to close the score to 13–10. (The pass was initially intercepted at the Bears' 2-yard line, but Frankian then grabbed the ball out of the defender's hands.) On the next New York drive, running back Ken Strong scored on a 42-yard touchdown run. Later an 11-yard run by Strong was turned into another touuchdown for the Giants, and they scored for a final time on Danowski's 9-yard run, a fourth unanswered touchdown.
New York outscored the Bears 27–0 in the fourth quarter to win 30–13.
