In a fantastic look at how the man who blew through $5 million in his first two seasons with the San Diego Chargers and is famous for having 10 children with eight different women, Cromartie explained to Bob Glauber of Newsday how he went from spending fast and furious to being frugal.
"Right now, I try to put away as much money as I possibly can and live on a budget," Cromartie said. "I learned the hard way."
That hard way was spending money non-stop, buying gifts for friends and giving away cash -- "lots of cash" as Glauber writes -- to friends and family members who would ask. There also was the nine-vehicle car collection, which included two Dodge Chargers, a '65 Caprice, two BMWs and two Escalades.
Now, after getting much-needed counseling from financial adviser Jonathan Schwartz, Cromartie is on a budget. His main car? A Toyota Prius.
The now fiscally responsible cornerback is trying to council younger NFL players.
"I tell the young guys, 'Don't spend any money the first year and a half of your career,' " Cromartie said. "You don't know what will happen after that. You might be released. You might be hurt. Just save your money."
After Cromartie's financial revolution, Schwartz said the cornerback's retirement is fully funded to age 100 and all his children will be taken care of through college.
It's a great story and a great lesson for rookies who suddenly are flush with cash. Those few NFL paychecks can last a lifetime if players are smart about it.
