Its not unusual for archaeologists to challenge each other with evidence based theories including at the Gihon Spring. Recently Dr. Joe Uziel discovered evidence that presented a similar time conflict. Under the north-eastern corner stone of the Bronze age citadel construction adjacent to the Gihon Spring, seeds were carbon dated by Weizmann Institute to the Iron age. The seeds were presumed to be in their original location, but if they had been washed under the corner stone, in a prior rain-storm the arguments over Iron or Bronze age dating would be futile.
To elucidate the futility, myopic archaeological reporting is often contained to single fragments of evidence that draw inferences absent of broader context discoveries found in proximity. For example Jerusalem's oldest constructed cave was probably a mansion carved into the east face of Mount Moriah, south of the upper Gihon Pool.

Further up the eastern face, a tomb containing ~4000 year old sophisticated tomb pottery was discovered by Parker-Vincent. Importantly this early Bronze Age tomb pottery dates Mount Moriah's first permanent population to a similar time in which the cave home on the eastern face would have been in use.

One of the most compelling observations echos a ziggurat like stairway the lower sections having been partly reassembled with steel staircase. Immediately adjacent, north of the cave, the base of the stairway was once quarried in sloping bedrock, but today it is a sheer-rock-cut-face that reshaped the natural slope of the bedrock to displace or destroy the arrangements that once provided gradual stepped-access from lower to upper ridge.

The slope may have first been reshaped to include steps for easier access on the ~30 meter rise (see profile image below) from the lower rock shelf, at the cave's natural entrance to the stairs leading to the high ridge. Interestingly, the lower section of stairs would have once landed on the east face of Mount Moriah, as it falls to the Kidron Valley, but the dramatic absence at the now sheer-rock-cut-face appears related to the quarrying that ultimately formed the large impassable void of the Upper Gihon Pool (see image below).
On the eastern bedrock, below the temple complex middle Bronze Age artifacts were discovered by Shukron and previous archaeologists, but several rooms built against the city wall (see image above) contained artifacts that were dated to the Iron Age.
The image above illustrates how access through the rear passage of room #1 of the temple complex led to the bedrock behind the wall. When the temple complex was excavated, several Iron Age artifacts were found in the passages and caused Ronny Reich to firmly date the temple complex to the Iron Age. However, it is evident these artifacts could have moved. The basement of the Iron Age rooms (above image) terminated on the bedrock as it descends east and like so many cavernous basements in and around the old city of Jerusalem the contents on the bedrock found the tunnel of room #1 where the Iron Age contents of the house slipped into and filled the space of the tunnel.
Based on the above,the definitive statements by Ronny Reich, as seen in the video below would therefore be an example of myopic archaeology. Eli Shukron has made public statements that the temple complex is a Bronze Age construct in direct opposition.
I'll leave it to you the reader to decide, which version is more likely just keep in mind that the standing stone or matzevah in room #2 (seen below) is most likely a relic from 3800 years ago, the the time of Israel's Biblical fathers, as such it is more likely to fit the context that supports the narrative of Eli Shukron.
