The Portsmouth Spartans (now known as the Detroit Lions) joined the league, while the Buffalo Bisons and the Boston Bulldogs both folded.
Defending champion Green Bay won its first eight games, including a 14–7 home win over the New York Giants on October 4.
In Week Thirteen, the Giants beat the Yellow Jackets, 14–6, while the Packers lost to the Bears, 21–0, cutting Green Bay's hold on first place to a mere 4/10ths of a percentage point, .769 to .765.
On December 14, the Packers scored on Red Dunn's touchdown pass to Wuert Engelmann, but the point after by Verne Lewellen failed, giving them a 6–0 lead.
After Chuck Bennett ran for a touchdown for the Spartans, the extra point attempt by Tiny Lewis was blocked, and when the game ended, the 6–6 tie gave the Packers the 1930 title.
