Your sitch is a judgment call & not being on that particular game, I can't really say as I did not see the play. HTBT

I did provide you with the rule though...

I didn't know we were talking about ME, but in my games as the T, I'm staying with the shooter even after I wave the shot off. If I judge that the defender hip checked purposely as opposed to incidental contact, then we've got an intentional foul.

If after the hip check the defender walks by or stands over the shooter & has something to say, perhaps it's a flagrant.
