Coach Nick got out on the court to explain the best way to defend the sideline screen and roll, using what Bulls coach Tom Thibodeau calls "ICE." Listen carefully during an NBA game and you'll hear the players and coaches scream "ICE!" or "Blue!" This means they want the on-ball defender to force the ball handler away from the screen.
This is truly the best way to guard the sideline screen and roll, because it contains the ball handler well and does not require a third defender to rotate over and help.
