I don't think your plan involves draft tampering. It would be more serious like a player faking a big injury in order to scare off other teams. In effect we have already stated (somewhere that I read) that we would not be taking Viney with our first pick. That is already out there so if GWS wants to bid they will get him.
And there is now way GWS would do a deal with us. They could not be trusted in any case,
