The guy's a piece of shi*, but unfortunately, his case is representative of a way bigger problem: how top paid athletes can get "high" on success and forget that they won't always be in the early blossom of their life, that their career can be cut short by one bad accident.
With all the sharks circling around them for x-y reasons, it sure ain't helping quite a few of them to have "steady legs" and I think that the big leagues should do a bit more for their athletes in that respect, with mandatory classes/formations about how to manage their money a tad smartly, with statistics in hands so they can grasp the seriousness of the situation.
