Sure, but those names have been known. SF has known that the available QBs were Fields, Lance, and Jones since before the trade. So, they may have loved one of those 3, and they may still like that one, but subsequent interviews, and/or deeper dives of players who went through the craziness of the Wuhan Flu year, may have pushed them towards another QB. I still don't see the problem.
Now, if the story was something like "49ers loved Jones, but did some more research and now think they really screwed up and that he's gonna suck in the NFL", that would be completely different.
