I agree and again the
Evidence for the historical existence of Jesus Christ page at rationalwiki shows the problem with such a minimumal Jesus:
Jesus as historical myth and The Tabula Rasa Jesus
Remsburg pointed out:
"A Historical myth according to Strauss, and to some extent I follow his language, is a real event colored by the light of antiquity, which confounded the human and divine, the natural and the supernatural. The event may be but slightly colored and the narrative essentially true, or it may be distorted and numberless legends attached until but a small residuum of truth remains and the narrative is essentially false."
So even if Jesus is a historical myth (ie was a flesh and blood man) you could have the issue of the Gospel narrative being essentially false and telling you nothing about the actual Jesus other than he existed--effectively putting him on par with Robin Hood or King Arthur, who have had historical candidates suggested as much as 200 years from when their stories traditionally take place.
To make Jesus more than
that a researcher has to assume
some parts of the Gospels narrative is essentially true.
But which parts? In answering that question all supporters of a "historical Jesus" get into the Miner problem of effectively turning Jesus into a Tabula Rasa on which they overlay their own views.

As I said before you could have Paul simply hear stories about some local preacher named Jesus whose efforts to create a following failed and who then drifted off never to be heard again.
Paul has his vision and in his mind creates his own Jesus.
Then years or decades later someone creates an elaborate life story for Paul's Jesus.
Sure you could argue that the Gospel account at its most basic level is plausible but there are many examples in known fiction where that is used to make the character more "real" so it doesn't really count for much.
In fact it can be argued it is in the details of the nonsupernatural events that suggest the whole Gospel account is a fiction. In this example the only thing to connect the "historical" Jesus to the Gospel one is the name...nothing else.
That is akin to saying that since you can find the name Clark Kent in a 1920's New York City phone directory that Superman must have been based on a real person. It doesn't come off as a plausible theory but an ad hoc theory to salvage a position that so devoid of actual evidence that no other reasonable action is left.
