IOW, JonBenet had been posed after death, probably in an obscene slouched sitting position to gain maximum shock value. The livor mortis settling in the dorsal area supports this. John doesn't want to admit it, but enough info from him slipped out during the police interviews to suggest it is probably what happened.
For instance, when John allegedly found JonBenet in the basement he said she was wrapped papoose style:
MIKE KANE: "Do you remember, was her head exposed? Were her feet exposed?"
JOHN RAMSEY: "Possibly."
MIKE KANE: "But not the rest of her?"
JOHN RAMSEY: "I mean, yeah, I think her feet were exposed. But her head was. Her head was tilted to one side. I was trying to hold her head."
Why was John trying to hold her head if she was lying flat on her back on the floor? It appears from his comment that she was not lying flat on the floor, but instead she was in a slouched sitting position. IMO he was trying to hold her head as he cut the cord so that the upper torso and head wouldn't fall over and hit the floor after the cord was cut.

a criminal profiler (I can't remember his name right now) has pointed out that if a sexual predator had wanted to display the victim for shock value, he would have done this openly (e. g. in the living room) and not have removed her far away into a dark and windowless room.
Even if we go along with your theory, there would have been no reason for John to lie about how he found her.
Why should he cover up forensic evidence in case an alleged intruder had killed JB? If he found her at around 2 am in the in wine cellar, why wait for three hours before calling the police? Why wait unless he wasn't involved?
Who do you think killed JB? An intruder? If not, do you think a family member 'posed' JB's body in a shocking way?
