Gogan was selected by the Dallas Cowboys in the eight round (206th overall) of the 1987 NFL draft,[3] as part of a change in the offensive line philosophy, when the team started to value size and strength over speed and athletic ability.
In 1992, he became a backup after Nate Newton was moved to left guard, in order to accommodate Erik Williams as the starter at right tackle.

[7] In 1998, he helped Garrison Hearst set a team rushing record with 1,549 yards and received second-team All-Pro honors.
