This was also Steve Young's last season in the league as he was forced to retire due to concussions.
San Francisco started the season with a 3–1 record and were heavily favored to win the Super Bowl but Young suffered his season- and career-ending concussion against the Arizona Cardinals in Week 3.
After defeating the Cardinals and the Tennessee Titans without Young, the 49ers went on to lose 10 of the remaining 11 games of the season.
Statistics site Football Outsiders calculates that the 1999 49ers had the second-worst pass defense they had ever tracked.
