As for Bill Walsh, I'd rate him a little better than the norm for that era, when the NFL was in the process of rapidly converting to a "whites need not apply ever again" policy at many positions that of course still holds true today with no sign of ending. Walsh's offense was more complicated than other NFL offenses, so he knew he needed players like Joe Montana, Dwight Clark and TE Brent Jones to help run it along with mostly white o-linemen. Fullback Tom Rathman joined the team in 1986 and was a key player on Walsh's third Super Bowl winner. Between '87 and '90, Rathman averaged about 750 combined yards per season running and receiving. At 6-1 and 230 pounds he obviously would have done some serious damage as the featured power runner for a team, but as it was he was one of a very few white backs touching the ball at all.ÂÂ
