To me this is the real problem manziel has.... some more info here about this "manager". Evidently he is more of a party buddy than manager and the fact that his parent's gave their blessing to this makes it even worse. http://bustedcoverage.com/2013/08/05/this-is-johnny-manziels-manager-uncle-nate/
Even if they can trace the money I bet he will take the hit and say manziel had no knowledge and thought he was doing it for charity or something. Hopefully either way they get rid of this guy and get him a real manager.
I hope Manziel plays, but if the bolded happens and Manziel is ruled eligible, then it's bullshit. Even IF Manziel honestly didn't know (and, let's be honest, why in the hell else would you sit and just sign sign sign so many autographs? What charity? Did he ask any specific questions?), you can't hire someone to be your "manager" and then feign ignorance of their dealings when it suits you.
