As the NFL's 2024 season approaches, the Denver Broncos and San Francisco 49ers face contrasting challenges. Despite an undefeated preseason, the Broncos have significant concerns about their defensive backfield, particularly after losing veteran safety Justin Simmons, and will rely on new talents like Brandon Jones and practice squad players to fill gaps. Conversely, the 49ers are seen as top contenders but have issues with their center position, which could destabilize their offense. Simulations by The Athletic project the 49ers to lead the league with 11.4 wins, while the Miami Dolphins are predicted to finish third in the AFC East, trailing the Buffalo Bills and New York Jets. Meanwhile, the Carolina Panthers are ranked last in terms of their trio of skill players, raising concerns about rookie quarterback Bryce Young's support system.
