Ronaldinho
Ronaldinho is the epitome of an athlete who had fantastic talent but partied too much. Perhaps it’s too strong to say he ruined his career because he has a World Cup winner’s medal. Meanwhile, he won a bunch of other trophies with Barcelona and PSG. But it’s safe to say his career declined because of his party antics (via The 18).

The Brazilian’s love for a good time is the stuff of legend. Perhaps the most dramatic saw him serve time in a Paraguayan jail because he entered the country on a false passport. But Ronaldinho had an incredible time behind bars because it wasn’t a proper punishment. The jailers brought him women and invited celebrity guests to drink with him at wild parties.
