That is fine as long as your opponents all run the same offense, have players of equal ability, and have the same tendencies in all rotations. Since this is obviously not the case, your team can benefit from the use of different blocking systems for different situations.
Some teams use four different blocking systems during matches.
Since most players are also trained to block in all three positions at the net, this gives us 12 different possibilities to use in any blocking situation. These different looks allow you to adjust to your opponent's tendencies in every rotation and also to hide a weak blocker on your side. 1.If you block the ball you don't need to worry about setting it. 2.If the other team's best player is hitting over your short blocker you aren't going to dig many balls to be set. 3.Your other players should have enough ball control to set a high ball in transition.
