Illegal defense?

[JoJo10]

First, thank you both for your replies!

I wanted to re-phrase some of my comments, as I see there is a more 'general' rule (Displacement) than a specific call. There is NO displacement going on by me, with or without the ball. When I have the ball on the low post off an entry pass, I'm assuming I have a right to the basket, as long as I do not 'displace' the man behind me guarding (ie. grabbing his arm or hooking with my non-dribbling arm); and also assuming his feet are not planted thereby drawing a charge!?

When I said 'boxing out', again, this is described as being in between the basket and the man asserting rebound position, assuming no displacement on my part. (I understand this is a judgement call by the ref).

Also, just for clarification crosscountry55, you wrote - 'puts a knee in your back'.
The maneuver is, the defender (man behind me) is putting his knee between my legs (not my back) where I can see his knee cap when i look down... AND using his thigh as a chair to lift me up. Again, no displacement on my part seeing as I cannot move because my feet are raised off the ground from his thigh.

If two players are pushing each other back-and-forth, i agree, this is good hard basketball; However, if both are pushing back-and-forth and yet the man behind is grabbing the shirt of the player he is guarding (with no displacement) that would be a foul if you see it, correct?

Gentlemen, again thank you for your response. So you know, I am not trying to debate, be combative or look for a reason to compensate for my height. You are the experts. I just want to make sure I am describing this clearly.

Thank you again for any further insight!
