Following a disappointing 4–7–2 season the next year, Potteiger was replaced by LeRoy Andrews. Before the 1929 season, Mara purchased the entire squad of the Detroit Wolverines, including star quarterback Benny Friedman. The Wolverines had finished in third place the year before. Led by Friedman, New York's record soared to 13–1–1. However, their lone loss was a 20–6 setback in November to the Green Bay Packers, and by virtue of this win, and their 12–0–1 record, won the NFL title. Following the season, Mara transferred ownership over to his two sons to insulate the team from creditors. At the time, Jack was just 22, and Wellington only 14.
