The San Francisco 49ers have made significant changes to their roster and coaching staff after last season's disappointing 6-11 record. Injuries played a crucial role in their struggles, particularly affecting special teams. Kicker Jake Moody, who was seen as a long-term solution, faced a tough season due to an ankle injury, finishing the year with a disappointing 70.6% success rate on field goals after a strong rookie performance. Moody expressed frustration with his performance in the latter half of the season, emphasizing that such results are unacceptable. The organization is hoping these changes will rejuvenate the team and avoid a repeat of last year's issues.
