Former Arkansas RB Darren McFadden recently announced his retirement from the NFL, hanging up his cleats after an up-and-down 10-year professional career.

Now, though, he’s filed a $15 million lawsuit against his financial advisor, Michael Vick (not the former NFL player), alleging Vick mishandled $3 million of McFadden’s money.

Per a report from ESPN.com, McFadden wanted Vick to use the money for a Bitcoin venture, but that never happened, as Vick used the money instead to fund his lifestyle.

According to investment fraud attorney Chase Carlson, had that $3 million been invested in Bitcoin as McFadden had wanted, it would be worth more than $200 million today:

McFadden said in the story that he shouldn’t have trusted Vick, saying he didn’t have McFadden’s best interests at heart:

“It’s just one of those deals with me as a young guy I wasn’t on top of my finances like I should have been and I trusted somebody to take care of everything for me and I don’t feel like at the time he had my best interest.”

The case has not been heard in court yet, so it remains to be seen how it all plays out. However, McFadden has a lot of money on the line as the case proceeds.
