San Francisco 49ers coach Kyle Shanahan expressed his disappointment after his team's loss to the Kansas City Chiefs in Super Bowl LVIII. The Niners have struggled in recent years, losing double-digit leads in Super Bowls and an NFC Championship Game. This marks their third consecutive Super Bowl loss since their last win in 1994. Although the team has experienced success in the playoffs, winning a championship has remained elusive. The players are determined to learn from their mistakes and come back stronger next season.
