Here are a few I recommend:
Offensive Scenarios
[Down by 1 with 5-10 seconds left]
Execute a quick-hitting play to create a high-percentage shot.
Emphasize options for a drive, pull-up jumper, or kick-out to an open shooter.
[Down by 2 or 3 with less than 10 seconds left]
Set up a play for a three-point attempt or a quick two-point shot followed by a foul.
Teach proper spacing and screens for creating open looks.
[Tied game with under 24 seconds left]
Practice playing for the last shot to prevent the opponent from having time to respond.
Emphasize clock management and choosing the best shot, not just the first available.
[Baseline or sideline inbound plays under pressure]
Practice inbounding against a full-court press or tight man-to-man defense.
Develop options for quick shots or advancing the ball upcourt.
[Needing a full-court play with less than 3 seconds]
Train for "Hail Mary" situations, including long passes and quick catch-and-shoot plays.
Defensive Scenarios
[Up by 3 with less than 10 seconds left]
Decide whether to foul or defend the three-point line without fouling. Practice both options.
Defending a one-possession game with less than 10 seconds
Emphasize switching on screens, denying the ball to star players, and not fouling shooters.
[Trapping to force a turnover]
Practice aggressive traps and rotations in situations where the team is down late and needs a steal.
[Full-court press after a made basket]
Drill full-court press scenarios to force turnovers when time is running out.
[Intentional fouling]
Teach players how to foul quickly and legally to extend the game.
Special Situations
[Managing timeouts and substitutions]
Practice scenarios where quick substitutions or timeout calls are necessary to set up a play.
[Free-throw rebounding]
Simulate situations where a team needs an offensive rebound after a missed free throw.
[Dealing with technical or flagrant fouls]
Prepare the team to stay focused and capitalize on free throws and possession changes.
How do you prepare your team for end of game scenarios?
