Plenty of people were out to get Tony Soprano, including his own mother. However, one that came closer than most was Tony's dear old Uncle Junior, who had his eye on the top spot within the 'family' that his nephew filled. The theory posited by WhyCutHair on Reddit is that on all the occasions Tony has diced with death, Junior was the cause of it. Early in the series, he put a hit out on his nephew, and years later, due to dementia, he mistook Tony for an old enemy, shooting him in his own home. The Sopranos superfan wrote, " the last thing Tony does before he goes to the restaurant, and if you adhere to the rational theory, he dies there, is to go see Junior in the asylum. So, maybe not directly, but Junior did jinx him for one last time.
While not as direct as Junior's previous efforts, it's an interesting idea given the prominence of superstition in the show. Christopher Moltisanti (Michael Imperioli) was notably rattled by the appearance of a bird at his initiation early in the series, and Paulie struggles to take a message from one of his former victims after visiting a clairvoyant. In the end, perhaps Tony's visit to his Uncle was one he should've missed, given that the powers that be had other plans and Journey on the jukebox.
