The team's disastrous 1975 season saw Sipe enter the starting lineup after three consecutive losses in which the Browns were outscored 124-26. Sipe's three starts reduced the margin of defeat for the squad, but still resulted in a trio of defeats, sending him back to the sidelines. The following year, he finally moved into a consistent starting role following an opening game injury to Phipps on September 12, 1976. As the team's signal caller that season, he led them to a 9-5 record, a six-game improvement over the previous season. 1976 was the team's second year under head coach Forrest Gregg.
