He started in the season finale at left guard in place of an injured Newton. In 1993, he beat out John Gesek as the starter at right guard. His role in one of the greatest offensive lines in NFL history was detailed in NFL Network's 2013 "A Football Life" episode "The Great Wall of Dallas". Before the start of the 1994 season, four of the Cowboys offensive linemen were free agents, so management focused on re-signing Newton. Gogan opted to leave and was replaced with free agent Derek Kennard. On April 17, 1994, he signed as free agent with the Los Angeles Raiders, where he was named the starter at right guard. He was a three-year starter and received his first Pro Bowl selection. On February 24, 1997, Gogan signed as free agent with the San Francisco 49ers. Although he didn't fit the team's offensive line scheme, he received Pro Bowl honors two years in a row at right guard. In 1998, he helped Garrison Hearst set a team rushing record with 1,549 yards and received second-team All-Pro honors. During the fourth-quarter of the 1998 Pro Bowl, Neil Smith took offense at Gogan going for his legs during a running play. As Gogan returned to the huddle, Smith hit him on the back of the helmet, which resulted in the first Pro Bowl ejections since the game was moved to Hawaii in 1980. On March 1, 1999, the 49ers had salary cap problems and traded him to the Miami Dolphins in exchange for a fifth-round draft choice (#157-Terry Jackson). In 1999, he reunited with former head coach Jimmy Johnson. He began the season as the starter at left guard, but he was later moved to the right side because of the play of Mark Dixon. He ended up in a platoon situation with Kevin Donnalley, alternating starts. He started 10 games and extended his consecutive games played streak to over 150 contests. On February 25, 2000, he was waived because of age and salary cap issues. On June 5, 2000, he signed as a free agent with the San Diego Chargers and started 14 games at right guard. On February 28, 2001, he was released and replaced with Kendyl Jacox. Gogan was named to three Pro Bowls and had a reputation as being one of the league's dirtiest players during his career. He is currently the NFL analyst for NBX.com and is also an assistant football coach for Mount Si High School in Snoqualmie, Washington.
