Thank you Earth's rotation?

Goal post is object B.  Also a in fixed point in in relation to the surface.

Kickers's plant leg meets the earth a point c.  Also a fixed point related to the surface.

Due to the plant leg being at point C all movement of the body including the foot making contact with the ball is also moving at a rate proportional to the Earth.

When the Ball is launched from that fixed point by way of movement still in proportion to the movement of the surface the ball continues to follow a path relative to all fixed point.

Meaning - All three objects (the kinking point, uprights and ball) are moving east to west at the same rate to point which is stationary relative to the center point of the earth (meaning not attached to the surface) due to laws of motion.

Incorrect interpretation of science by the astrophysicist unless there is something I am missing.

This was just a slapped together quick response compared to how I have this in my head but I think I stated it clear enough.  Too busy to go into the longer explanation.
Your missing the ground speed being different at different lattitudes.

Here's a good simple explanation of the Coriolis Effect and Tyson's point:

B. I Feel The Earth Move Under My Feet: North/South Motion
Without premise 3, you can still pretty convincingly describe the Coriolis Effect on objects moving due north or due south.
The Earth rotates to the east at an effectively constant angular velocity, but different latitudes have different linear speeds. A point at the equator has to go farther in a day than a point in Ohio, so it must go faster.
However, when an object starts to move north or south and is not firmly connected to the ground (air, artillery fire, etc) then it maintains its initial eastward speed as it moves. An object leaving the equator will retain the eastward speed of other objects at the equator, but if it travels far enough it will no longer be going east at the same speed the ground beneath it is.

The result is that an object travelling away from the equator will be heading east faster than the ground and will seem to be forced east by some mysterious force. Objects travelling towards the equator will be going more slowly than the ground beneath them and will seem to be forced west. In reality there is no actual force involved, the ground is simply moving at a different speed than the object is "used to".
Consider the diagram to the right. The orange arrow represents some object sent north from the equator. By the time it reaches the labeled northern latitude, it's gone farther east than a point on the ground would have, since it kept its eastward speed from where it started. Similarly, the yellow arrow started away from the equator at a slower eastward speed, and doesn't go as far east as the ground at the equator...seeming to deflect west from the point of view of the ground.
