See Defences - 1-2-1-1 Tennessee, Maryland, Canada, Alan Lambert, also Kentucky and Thumbs up (trapping off the dribble).
X2 and X4 trap an inbounds pass to 1, X1 and X3 are the interceptors, protect strongside and middle, X1 covers the sideline.
Bruce Pearl - don't trap an inbounds pass to the weakside, it's too far for X4 to run.
Billy Tubbs - always trap the inbounds pass, even to the long corner.
Interceptors X3 and X1 are guarding three attackers, they read the passer's shoulders to position themselves.
X3 may be able to steal a pass back to 4, but don't give 5 the middle of the floor.
Variation - X3 moves up to cover ball reversal, X5 covers 5, leaving open a skip pass to 3.
Canada Basketball - a pass back to the inbounder is often least contested by interceptor X3, especially if the inbounder is a post player who is not a threat to dribble the ball.

Jim O'Brien - the press stays on for any backward pass.
Get back to a 1-2-1-1 set on ball reversal to 4, X1 mirrors the ball, covering middle, X5 protects the basket (4 could throw long, he is not double-teamed).
If 4 is an early match-up, pressure the ball, make him put it on the floor, X2 or X3 will trap with X4.
If 4 is a dead match-up, get in the passing lanes, make him make a play.
Rick Pitino - if the inbounder is the other team's center (their 5), the diamond moves back and plays the passing lanes, otherwise the inbounder is pressured, encouraging an uncontrolled dribble.
Dean Smith - usually the inbounder is a big not known for his dribbling ability, if the inbounder is a dribbler, X4 could contain him with help from X2 and X3.
See Defence - 1-2-1-1 thumbs up (trap if 4 drives the ball).
If 4 passes to 3, X3 and X4 trap, X1 covers the sideline.
See Defences - 1-2-1-1 Kentucky, Alan Lambert, also Canada (X5 covers the sideline).
