How to create FBSO formula for a certain player by rotation?

I want to find out what % we sideout (Not FBSO) when we set a certain player in a rotation. For example, what is our SO% when we set #16 in rotation 1?

This formula tells us what our SO% is when we set the ball to the
a particular player during this action:
=VSCOUNT(VSAND(VSCELL("*(2)A;WR-0;*Z(1)",$I3,$K2),"*E;B-0","aS;B-1"))/VSCOUNT(VSAND(VSCELL("*(2)A;*Z(1)",$I3,$K2),"*E;B-0","aS;B-1")) ,
Here in cell I3 we have the number or rotation that we need, and in
K2 we put the player's number.
