No. 9: Running back Delvin Williams
The No. 9 slot on the list goes to one of the 49ers’ first second-round draft picks in post-merger team history. San Francisco selected running back Delvin Williams out of Kansas with the 49th overall pick in the 1974 NFL Draft.
After a rookie season that saw him have a limited impact (just 37 total touches for 210 yards, although he did score three touchdowns), Williams went on to lead the 49ers in rushing for the next three seasons, maxing out at 1,203 yards on 248 carries in 1976.
During his time in San Francisco, the 49ers were not very good, with only one winning season (1976) in his four years as a Niner, before finishing off his NFL career in Miami, where he garnered his only All-Pro season in 1978.
Williams finished his time as a 49er just short of 3,000 yards rushing, good for 12th in team history. He was certainly a fantastic back. Given his lack of longevity and impact on the team in terms of wins, while he cracks the top-10, ninth feels like the ideal place for Williams on this list.
