As more info comes out, it looks like his buddy/personal assistant Nate is the one who said manziel will need to be paid for any autograph sessions. It's possible though unlikely that if payment was made nate is the one who is getting the cash and was using manziel and thinking he found a loophole and manziel never saw a dime.
Nate is the guy who said the racial slur that got Johnny into the fight a year ago.
<sigh> why do these guys put themselves in the hands of their buddies who don't know what the hell they are doing??
