I think the OP is on the money, slight leaks are now emerging about other clubs ie: 7.30 report. Charters involvement must be investigated, but of course no one in power would want to see that. The media management of this saga makes me sick.
The worst for the clubs would be that Charter may be involved with 2 or more players at particular clubs without that club's knowledge.
It would be much easier for Charter to hawk his wares to individual players than go to an AFL club doctor.
