You may be right as the article you've provided is by Ryan Fowler of Bleacher Report and dated July 7th, 2024. To your point, that's a made-up trade idea.
However, the You Tube Video by News Express - The Saints Report - orator states that "Justin Panadero from Bleacher Report has suggested that the Vikings might be looking to acquire New Orleans Saints cornerback Marshon Lattimore." Could there be substance coming from a second voice possibly hearing it elsewhere or could it merely be a colleague regurgitating something and growing artificial legs underneath it? Probably the latter. Either way, the door won't be shut on the subject this year at least until November 5th, 2024.
