In 1971, the 49ers had a particularly good year on defense, allowing only 216 points (15.4 points/game), 6th least in the NFL, and won the NFC West with a record of 9-5. They won their divisional game of the 1971 NFL Playoffs over the Washington Redskins, allowing only 99 yards rushing and 93 net passing yards, but again lost the NFC championship game to Dallas. In 1972, San Francisco won the NFC West for the third straight year with a record of 8-5-1, allowing on defense 249 points (17.8 points/game), 9th in the league. But they lost their divisional game of the 1972 NFL Playoffs to Dallas, thus eliminated by the Cowboys three consecutive years. In those three years, Wilcox at left side linebacker formed a strong tandem with middle linebacker Frank Nunley and right linebacker Skip Vanderbundt.
