We last wrote about Patriots tight end Rob Gronkowski on June 18. The biggest stories surrounding the team three weeks ago? 1. If Gronk's latest surgery would force him to miss the regular season, and 2. Tim Tebow.

Then former teammate Aaron Hernandez was charged with first-degree murder in the shooting death of Odin Lloyd, and current teammate (though that could change, too) Alfonzo Dennard was arrested on suspicion of DUI.

On Thursday, Gronk and his brothers were in Boston promoting his book, "Growing Up Gronk," where he faced the inevitable questions about a tumultuous few weeks for the Patriots.

As for "Growing Up Gronk," Amazon.com offers this description: "This unique story of the NFL's new first family reveals the secrets to the Gronkowskis' collective success and opens the door on a one-of-a-kind household, a veritable incubator of athletic greatness."
