and moved the team to Cleveland where they became the Cleveland Bulldogs during the 1924 NFL season. With Chamberlin still serving as player/coach, the Bulldogs compiled a 7–1–1 record, outscored opponents by a total of 229 to 60, and won their third consecutive NFL championship. After the 1924 season, Chamberlin was again selected as a first-team All-Pro by Collyer's Eye and a third-team All-Pro by the Green Bay Press-Gazette. In three seasons with the Bulldogs, Chamberlin led the franchise to three NFL championships and a record of 28-1-4, having outscored opponents by a combined total of 659 to 94. Dave Noble, who played for the 1924 Bulldogs, explained Chamberlin's coaching success as follows: "Guy Chamberlain knows as much or more football than any other coach in the country. Moreover, he has a faculty for getting the most out of players, not because he is a driver, for he isn't that sort, but because they like him and will do their utmost to please him by playing hard." Frankford Yellow Jackets In 1925, Chamberlin joined the Frankford Yellow Jackets in Philadelphia as player and coach. He led the 1925 Frankford team to a 15–7 overall record, 13–7 against NFL opponents. The team had compiled a 9–1 record in its first 10 games, but Chamberlin suffered a broken shoulder in a game against Akron, and the Yellow Jackets lost six of the next eight games. Chamberlin returned to the lineup in mid-December and led the team to victories in its final two games. In 1926, Chamberlin returned to Philadelphia and appeared in all 17 games as a player, despite being the oldest player on the team at age 32. He led the 1926 Yellow Jackets to an NFL championship with a 14–1–2 record, shutting out 10 NFL opponents and outscoring all NFL opponents, 236 to 49. On December 4, 1926, the Yellow Jackets defeated the previously unbeaten Chicago Bears, 7–6, to secure the championship. In a 1968 book titled "Pro Football's All-time Greats", the author wrote that Chamberlin blocked both an extra point and a field goal in the victory over the Bears, though contemporary accounts do not corroborate the claim. In two years at Frankford, Chamberlin led the Yellow Jackets to Philadelphia's first NFL championship and compiled a 27-8-2 record against NFL opponents. Chicago Cardinals In August 1927, Chamberlin signed as player/coach for the Chicago Cardinals. With the exception of Ben
