Making a call in your partners area.

[ca_rumperee]

... in terms of PCA. 2 man mechanics.

I am trail.
Ball is in corner in front of lead. I am closing down watching all action outside the lead's corner, predominantly in the key.

Player in corner drives to the key, or passes to post player who turns into the key. In both instances I'm not really talking about along the endline, but rather towards the area between ft line and basket. Play is coming at me, and I know my partner will often have a view of nothing but player's backsides.
If I have a foul there, I call it. That's just been my approach this year. Haven't really had any conversation with anyone about it.

Am I poaching, or is the key 'mine' in the above scenario?
