Outhouse,
As I said, I haven't thought about this issue in 15 years and am open to revisiting it.
I read the article you linked to and I don't see how it applies to this discussion. Schiffman compares Josephus' description of the Temple with the description of the idealized Temple in the Temple Scroll and he concludes that:
There is absolutely no chance that Josephus used the Temple Scroll or the architectural plan included in it as a source.
The ideals of the architect of that plan for a gargantuan, redesigned Temple were never realized, even when Herod's architects rebuilt the Temple.
The Herodian architects made no use at all of the Temple Scroll.
Josephus' plan for the Solomonic Temple resulted from biblical interpretation with only minimal influence from the existing Temple of his day.
The description of the Herodian Temple by Josephus derived from direct information/observation of its architecture. Unlike the description of the Temple Scroll, Josephus' accounts represented reality, not utopia. Those of the Temple Scroll represented utopia, not reality.
Also, this statement you cited appears to be in line with what Sagiv is saying.
The measurements given by Josephus, namely that each side of the Temple enclosure was the length of a stade, which is between 585 and 660 feet, seems to indicate a dimension which agrees neither with that of the Mishnah nor with that of the present-day Temple Mount enclosure which may have been expanded somewhat during the Islamic period.
In other words, the Temple Mount enclosure we see today is larger than the one that Josephus and the Mishnah describe (whether it was expanded by Hadrian or during the Islamic period or whenever).
As for parroting Sagiv, I have to do all of my internet use on my days off with the two hours that the library gives me, so I haven't had enough time to expand on what Sagiv is saying (on top of the emailing and research I need to do on other issues), but in any event you haven't answered what I've cited to my satisfaction.
As for Sagiv's credentials, I like to focus on the merits of an idea, and the article you linked to (and the quote you gave from it) actually to lends support to Sagiv's idea by saying that the Temple Mount is larger today than described in the ancient sources.
I also mentioned Goldberg's summary of Josephus, in which he notes that, "Titus orders
the whole city and Temple to be razed to the ground, leaving only the tallest towers and a small portion of the wall on the west," and here is Josephus' description in War 7.1.1.
Caesar gave orders that they should now demolish the entire city and temple, but should leave as many of the towers standing as were of the greatest eminency; that is, Phasaelus, and Hippicus, and Mariamne; and so much of the wall as enclosed the city on the west side. This wall was spared, in order to afford a camp for such as were to lie in garrison, as were the towers also spared, in order to demonstrate to posterity what kind of city it was, and how well fortified, which the Roman valor had subdued; but for all the rest of the wall, it was so thoroughly laid even with the ground by those that dug it up to the foundation, that there was left nothing to make those that came thither believe it had ever been inhabited. This was the end which Jerusalem came to
