Why some call Kick Ball and others don't!!!

[MREUROREF]

I've heard officials say, "When the game is tight, players are half court pressing, and it's the last few minutes of the game they would let some of those calls go. (ie. kick ball, minor travelling when there is pushing, three seconds, small step inbounds after basket with no pressure, etc.)

Some philosophy about call/no call okay, some will debate, however the Kick Ball Violation; does anyone agree with this?

Okay, if the defender purposely puts his leg out then blow; but if the defender is hustling and the (a) ball hits leg or (b) the ball is on the floor, pinballing around, and is kick by defender. What's the call? Do you need to judge intent or advantage/disadvantage? Like some other calls...and finally how do you think your commish/assignor would respond to similiar violation such as:

(ie. kick ball, minor travelling when there is pushing, three seconds, small step inbounds after basket with no pressure, etc.)

And with the playoff games coming, you want to look as competent as possible without giving the game a text book answer feel.
