Football may be the most popular sport in the United States, even a religion for some, but it can have a darker side. Several high-profile criminal cases implicated NFL players: O.J. Simpson, the most famous, accused of having murdered his ex-girlfriend; Deshaun Watson, quarterback of the Houston Texans, charged by 21 women of sexual assault; Michael Vick, who organized dog fights in his spare time. Unbearable daily pressure, omnipresence of the media, painful family history... There seems to be no shortage of reasons to fall on the wrong side of the fence, although it is difficult to make generalizations. Nevertheless, there can sometimes be a kind of double game. Shining on the field and in front of the cameras, and behind the scenes... darkness.
