Over the past 24 hours, several key insights and recommendations have emerged for fantasy football managers as they prepare for Week 12 of the 2024 NFL season.

## Risky Starts
Several players are considered risky starts due to various factors such as matchups, team dynamics, and recent performance.

- **D’Andre Swift (RB – CHI)**: Facing the Vikings, Swift's value is uncertain due to the potential for a pass-heavy script and the Vikings' strong defense against running backs[1][5].
- **Kyren Williams (RB – LAR)**: With the return of Cooper Kupp and Puka Nacua, Williams' role has diminished. The Rams' tendency to pass in neutral game scripts and the Eagles' strong defense against running backs make Williams a risky start[1].
- **Chuba Hubbard (RB – CAR)**: Despite being a valuable play this season, Hubbard faces a tough matchup against the Chiefs, who allow the fewest fantasy points to running backs. Additionally, the potential debut of Jonathon Brooks could reduce Hubbard's touches[1].

## Safe Starts
On the other hand, some players are highly recommended due to favorable matchups and consistent performance.

- **Justin Herbert (QB – LAC)**: Herbert is in a prime position to excel against the Baltimore Ravens, who have given up the third-most fantasy points to quarterbacks this season. The Ravens' strong run defense and weaker pass defense make this an ideal matchup for Herbert[2][3].
- **Justin Jefferson (WR – MIN)**: Despite a challenging matchup against the Chicago Bears, who allow the second-fewest fantasy points to receivers, Jefferson's high volume of targets and consistent performance make him a safe start[3].

## Sit Recommendations
Some players are advised to be benched due to unfavorable matchups or recent performance.

- **Nick Chubb (RB – CLE)**: Chubb has not performed as well since his return from injury, and this trend is unlikely to change in Week 12[2].
- **Jakobi Meyers (WR – LV)**: With the emergence of rookie tight end Brock Bowers as the team's top receiver, Meyers faces a tough matchup against the Denver Broncos, who have allowed the fewest fantasy points to opposing receivers[3].

## Bye Weeks and Lineup Decisions
Week 12 marks the beginning of a challenging period with multiple teams on bye, which will force fantasy managers to make tough lineup decisions. Six teams will be on bye this week, followed by another set of bye weeks in Week 14 after a brief reprieve in Week 13[1][3].

In summary, fantasy football managers need to carefully evaluate their lineups, considering the risks and rewards of each player's matchup and recent performance, especially with the looming bye weeks complicating roster decisions.
