Saquon Barkley's new ad trolls Giants owner John Mara over Hard Knocks moment

All of John Mara's worst fears about losing Saquon Barkley to the Philadelphia Eagles have come true this season, as the former Giants running back is having the year of his life, rushing for over 2,000 yards.

The Giants owner went viral over the summer after he was caught saying "I'll have a tough time sleeping if Saquon goes to Philadelphia" during an episode of Hard Knocks: Offseason with the New York Giants.

Sure enough, Barkley went to Philadelphia, and it's gone even better than they could have hoped for. Now, the running back is trolling Mara in his new ad for Unisom -- a product to help people sleep better.

"I heard some of you were having trouble sleeping, so I wrote you a lullaby," he said in one of several ads posted to his Instagram story. "Rockabye baby, awake in your bed. As the thought of 2,000 swirls in your head. It sure is tough to lose sleep over football. Not for me, though. Good night to you all."

He didn't mention Mara by name, but he didn't need to. The message was loud and clear.
