Rob Gronkowski compared Bill Belichick to “the Grinch” during his “NFL on FOX” commentary this season, so it only seems fitting that “Santa Gronk” created a book called “How the Grinch Won 6 Rings” to explain why!

Gronk went all out on this book that includes illustrations!  This could be his new side hustle… narrating books! LOL
