Rob Gronkowski
‘Gronk’ loves a party but that doesn’t mean that the legendary tight end splashes the cash. The Super Bowl winner is one of the few NFL players who manages his money sensibly. He refuses to spend any of his contract money and saves it all. Instead, he uses his endorsements to fund his lifestyle (via Kiplinger).

He knows that money doesn’t last forever and that it is more difficult to earn cash after a playing career. That’s why Gronkowski and his family enjoy relatively simple lives. It doesn’t mean that they don’t eat in nice restaurants or have amazing holidays. But he holds back on buying the latest Lamborghini because it’s a waste of cash.
