No I'm not saying anything about USC itself. It is a thing the players do on their own of course.
This kind of thing is commonplace throughout football and IF this report is true, my first thought is I'm surprised they didn't do a better job of masking.
So far, we have only seen this info from one source. nfldraftbible.com. Who the hell are they? Everyone is acting like this info just came off the AP news wire.
For all we know at this time, this could be misinformation being put out there by some team hoping to get these players to more likely fall to them on draft day.
