This is an excellent quick hitter the Sacramento Kings ran during the 2013 NBA Las Vegas Summer League. One of the options not drawn is for 4 to slip hard to the rim if X4 jumps out hard to help on the flare screen for 3.
The shot for 2 is more likely in high school or college because X2 is allowed to sit in the lane and help, whereas in the NBA they can only sit there for 2.9 seconds.
