Boxout?

[Luv4Asian8]

Situation: Rec Ball (so we know they're big babies). "A" (forward) comes into post to receive ball, posting up again a giant of center, "B". All night, A tries to boxout B, but can't budge him (hehe...looks really funny, but o well). As the game goes on, get's a little more physical in the key.

Question: Considering there was no displacement, I didn't blow whistle. But in hindsight, should I have? I mean, to prevent it from getting so physical later on in the game when calls really start to count.

How does an official's consistency play into this? If we have not been calling it all night, should we begin now?

just wondering....thanks
