After Casey was traded to the Los Angeles Rams in 1967, Witcher moved into the starting lineup and led the 49ers with 46 receptions.
With John Brodie having an MVP season and the 49ers with a solid defense, the team won its division with a 10–3–1 record, qualifying for the playoffs.
Witcher scored the 49ers lone TD the following week against the Dallas Cowboys in the NFC Championship Game at Kezar Stadium.
After an 18 reception season in 1971, the 49ers looked to upgrade the wide receiver position opposite Gene Washington.
Down 17–6 in the 4th quarter, Brodie came off the bench after an injury to throw 2 TD passes to win the game and the division title.
