I think Nightengale is the most full-of-s*** writer out of all the big story news guys. He's always commenting on every rumor, but it's extremely rare for him to ever actually break any trades. Far more often than not, he spews garbage that never materializes into anything.
We already know that the Jays don't often trade for guys they're rumored to be in on, we know they don't have much interest in rentals, and Nightengale has never provided reliable information in regards to the Blue Jays. Taking all that into account, we can probably safely assume that he's making up what he's heard, or somebody told him to leak the Jays name to maybe push a player's value.
Don't believe anything you read about the Jays until it happens.
