That's because Heyward-Bey, with the help of his mother, who is a certified accountant, has been frugal with his nearly $35 million in career earnings, according to ESPN's Jeremy Fowler.
Heyward-Bey made nearly $30 million in his four years with the Oakland Raiders prior to a stop in Indianapolis in 2013 and then joining the Steelers in 2014. They re-signed him this previous offseason.
The 29-year-old receiver has managed his money closely, saving "most" of it, according to Fowler. Darrius and his mother designed a monthly allowance for him and he pays her a commission to help manage his money and track his expenses.
"I get an email [from her] every Tuesday," Heyward-Bey told Fowler. "I can read it over, check it up. I see where the money is going."
Heyward-Bey also explained that he's able to continue to save because of his simple lifestyle.
"I don't have any kids and I'm not married, so the money I spend is on me. It's really easy to say no to myself. I keep things real simple. I'm not really a flashy guy. I understand what I want to buy. I invest my money well and pay my taxes."
According to Fowler, Heyward-Bey even shuts off the cable in his California home for the six months of the year he's not there.
Heyward-Bey is just one several financially savvy NFL players. In October, Detroit Lions safety Glover Quin revealed that he's doubled his earnings by investing 70% of his NFL salary.
As always, more players in all sports should follow the leads of Heyward-Bey or Quin to secure their future.
