Low Post Action

[Almost Always Right]

It seems like Rough Post Play is a POE every year from the NCAA and the NFHS. There were rules cited earlier in this thread.
Also there are a couple of hot buttons you need to be aware of: 2 out of is said to be automatic. i.e. 2 hands, a forearm and a knee, etc.
I have had good luck doing some preventive officiating in the past, such as the first couple of times down the court(even if they are not doing anything at that point) step in close to them in the L position and communicate with them so they know right off the bat that they have your crews attention. I try to say things like, "Watch the bows." or "Hands off" or "Use your feet" or "Don't dislodge". Of course if they choose not to listen then at least you have had your attention on them and can probably get that first one as opposed to having to go double.
A double foul can definitely get everyone's attention though.
