Did You Know Gronk Hasn’t Spent One Cent of His NFL Earnings?

In a new memoir, Rob Gronkowski reveals that he hasn't "touched a dime of his signing bonus or NFL contract money." So how does the 23-year old super athlete party animal do it?

Gronk makes enough money with endorsement deals with the likes of Dunkin Donuts, and BodyArmor SuperDrink that he doesn't need to dip into his salary.

To this day, I still haven’t touched one dime of my signing bonus or NFL contract money. I live off my marketing money and haven’t blown it on any big-money expensive cars, expensive jewelry or tattoos and still wear my favorite pair of jeans from high school… I don’t hurt anyone (except Gord with the occasional kick to the groin), I don’t do drugs, I don’t drive drunk, I don’t break the law… I’m a 23-year-old guy just looking to have a fun time.

The memoir titled 'It's Good to Be Gronk' is due out in July, and is available for pre-order at a variety of online retailers.
