1. Tom Rathman 1986-1993 (nine postseason victories, 2x Super Bowl champion)
After drafting running Roger Craig, Bill Walsh once again drafted a running back out of Nebraska who had less than 20 receptions in his four-year college career. And once again, Walsh shaped that running back into a multi-dimensional threat in the Niners’ backfield.
An excellent blocker and short-yardage back in college, Rathman became yet another talented receiving option out of the backfield in Walsh’s offense. Rathman quickly became the prototype for all fullbacks who came after him. At his peak, there was no one better in the NFL at the fullback position than Tom Rathman.
Two Super Bowl victories and two touchdowns in a Super Bowl win against the Denver Broncos put Rathman in the top spot at fullback for the San Francisco 49ers.
2. William Floyd 1994-1997 (five postseason victories, Super Bowl XXIX champion)
Fullback William “Bar None” Floyd fit perfectly into the Niners’ recent tradition of versatility in the offensive backfield. Although the 49ers didn’t ask Floyd to play a prominent role in the team’s blowout victory in Super Bowl XXIX, the fullback was instrumental in getting San Francisco to the big game during his rookie season. Essentially, Floyd was Tom Rathman redux.
Floyd received his nickname from his agent, who said his client was the best fullback in football, “bar none.” When healthy, Floyd was the best player in the game at his position. Unfortunately, the former first-round draft pick suffered a career-altering knee injury that limited the fullback from having a longer NFL career.
