kyle korver's 4stance type is A2
A1 ( cross type )
2 motion , hold with fingers, turn before, deep dip, index finger release
A2 ( parallel type )
2 motion , hold with fingers, turn in the air, deep dip, middle finger release ( fork )
B1 ( parallel type )
1 motion , hold with palm, turn in the air, shallow dip, middle finger release ( fork )
B2 ( cross type )
1 motion, hold with palm, turn before, shallow dip, index finger release,
His release is middle finger (parallel type)
dipping the ball at the center of his body (parallel)
His shot power comes from toes(A2 type)
with 2motion shot, deep dip
shows he is a A type
Putting all these together this is he is A2 type in 4stance theory
