Usually the player setting the seal at the shooter position is a big physical player, able to drive their check backwards with their body momentum.
Both players should be on their proper floor sides, and the fifth player off of the bench should be one of the team’s premiere shooters (see play makers). The pass can come from any player on the far-side.
This play can actually be run at any time in theory, whenever the ball is on the strong-side.
In reference to the offensive end of the floor, whereby three or four offensive players “overload” one side of the floor, leaving one player on the opposite side with plenty of space to try a one-on-one move towards the net.
This play is an attempt to isolate a team’s best one-on-one offensive player (play maker), against a mediocre defender.
On defense, yelling “Iso” alerts all other defenders to be prepared to help the isolated defender.Be especially wary of this play during 4-on-4 situations (see Defense Drill #13B - Variation #3).
