A call is a call. You foul a guy it doesn't matter how big you are it's a foul. Shaq had all the moves. Shoulder into your chest to move you out of the way, elbows to the head while looking like he's just lifting the ball up, the elbow hook sweep to get around his man, the clearout with his left on his one handed jumpers, the steam roll right through you move. I'm sure I missed some, but the whole thing with him getting away with offensive fouls was quite well discussed back in the 90's.
OK, but now you are changing what you originally stated. You said that the refs let him get away with it, which is different to this post. I think the opposing player reaction is why people react to this so much but you see it and have seen it per position throughout the history of the league. If anything, at least you knew players didn't pretend to flop

.
So yes, true, a call is a call but does the nba define what the rule is per player given all are different? No, one rule under human interpretation. If a player could easily absord the contact in the post would the same call be made? It hardly does. Do you think KG & Bynum are evaluated the same in the post? Big bodies with large mass make a bigger splash.
Why this becomes a negative for Shaq, I do not understand? Shaq pushed this to the extreme but he also got called for many offensive fouls which were not as a result of this. To the point where he could barely make any contact or get position without the ref's blowing the whistle. I am not going to penalize him for something the league had to call. And let's be honest, depending on what side of the fence you are on with Shaq, is the one you will remember.
This was pre-flopping, I'm talking about games before Vlade and the likes resorted to flopping. If they called Shaq for all his offensive fouls he'd have been in trouble a lot and the league doesn't like stars on the bench. They want them scoring points.
Don't agree with this. Did you see how many fouls he picked up over his career?
Strength has nothing to do with fouling. Just because you are strong doesn't mean you don't have a normal gear. You know Shaq can safely handle a baby if he had to right?
True but mass combined with strength certainly does and especially when for most of the times you look like a man among boys. So if you played against someone 60-70 pounds lighter, weaker base etc, you'd turn down your game?
And Mike Tyson could shake your hand nice but was he expected to tone down his left?
A lot of that came later. It was trial and error with trying to shut him down. The refs let him move you out of position illegally so they started improvising.
Take a look at this game. It's the first one I found with Shaq as a the focus from his Orlando days but I'm sure I could find better if I took the time.

1:03 Shoulder, elbow clear out
Those are just a couple.
Well picking a game versus Lattner is always a great starting block

Look, I have already said that yes it happened but to act like this was the sole reason for Shaq's post success is ridiculous. I've played a lot of ball versus guys taller and with more mass than me so unless there becomes a post force generator physics is physics. And as it turned out to be a professional league had problems identifying too much or too little with him.
I am still trying to understand the point you are looking to make? Is it Wilt wouldn't be Wilt, MJ, MJ, Shaq, Shaq, Kobe, Kobe etc all without the aid of superstar calls? And these so-called calls make these superstars who they became?
