The Rhinos' football announcer was voiced by sportscaster Dick Enberg, who at the time was the voice of the Los Angeles Rams. Alan Reed had a recurring role as Mad Dog Maloney, the Rhinos' coach. The Huddles had a dog named Fumbles, voiced by Don Messick. Fumbles, much like Muttley, would often laugh at someone's misfortune, but whereas Muttley's laugh was wheezy in nature, Fumbles' laugh was more guttural. Most of the in-game action consisted of recycled animation (a shot of the team's running back side-kicking and stiff-arming defenders was one shot that was particularly frequently used).
