Very false.
Jones only has 3 fights under USADA testing: OSP, Cormier #2, and Cormier #3. He failed drug tests for PEDs in the last 2 fights and looked awful against OSP. So our only sure baseline for a clean Jon Jones is the OSP fight. Every other fight prior had pathetically inadequate drug testing.
So if Jones against OSP is a version of 'clean' Jon Jones, I think he loses to Gus, Cormier, and Anthony Johnson. He probably beats everyone else, but I think he loses to those 3 guys without PEDs.
