Your implication is that because a story contains no named sources, the information is not legitimate, or not reliable. I would submit to you that this is exceedingly rare at a reputable newspaper like the New York Times, and although all newspapers are sometimes mislead by their sources, or otherwise get things wrong, when this happens at a paper like the Times, it is universally followed by a correction.
In other words, the Times is not going to print a story based on anonymous submissions without any further vetting, or investigation. They're going to seek independent corroboration, they're going to involve other experts, and they're going to ask questions of the principals.
