more. The Browns, who lost the last game of the regular season to the Lions only a week before, won their second NFL championship 56–10. "I saw it, but still hardly can believe it", Lions coach Buddy Parker said after the game. "It has me dazed." Cleveland's success continued in 1955 after Brown convinced Graham to come back, arguing that the team lacked a solid alternative. Cleveland finished the regular season 9–2–1 and went on to win its third NFL championship, beating the Los Angeles Rams 38–14. It was Graham's last game; the win capped a 10-year run in which he led his team to the league championship every year, winning four in the AAFC and three in the NFL. Rams fans gave Graham a standing ovation when Brown pulled him from the game in the final minutes. Without Graham, the Browns floundered in 1956. Injuries to two Browns quarterbacks left the relatively unknown Tommy O'Connell as the starter, and Cleveland finished with a 5–7 record, its first losing season. Dante Lavelli and Frank Gatski retired at the end of the season, leaving Groza as the only original Browns player still on the team. While the Browns' on-field play in 1956 was uninspiring, off-the-field drama developed after a Cleveland-based inventor let Brown test a helmet with a radio transmitter inside. After trying it out in training camp, Brown used the helmet to call plays during the pre-season with long-time backup George Ratterman behind center. The device allowed the coach to direct his quarterback on the fly, giving him an advantage over franchises who had to use messenger players to relay instructions. The Browns used the device off and on into the regular season, and other teams began to experiment with their own radio helmets. Bert Bell, the NFL commissioner, banned the device in October 1956. Today, however, all NFL teams use in-helmet radios to communicate with players. Jim Brown era and new ownership (1957–1965) With Otto Graham and most of the other original Browns in retirement, by 1957 the team was struggling to replenish its ranks. In the first round of that year's draft, Cleveland took fullback Jim Brown out of Syracuse University. In his first season, Brown led the NFL with 942 yards of rushing and was voted rookie of the year in a United Press poll. Cleveland finished 9–2–1 and again advanced to the championship game against Detroit.
