5:12 PM PT -- Jon has responded to the claims DC made to TMZ Sports ... saying "Been a lot of GOAT talk this week, I guess Silva and I are out of the running, I wish my competitors would campaign by simply fighting me instead of switching weight classes and talking s**t from a distance"
"People believe USADA when they say they found something, but choose to not believe USADA when they say it was discovered by the worlds most powerful microscope’s/scientists and had absolutely zero performance enhancing benefits."
He continued ... "I get it, when I was younger people blamed me getting my hand raised on having long arms, eye pokes and having brothers in the NFL."
"I just laugh, continue to work, continue to give glory to God and continue to win. That’s all I can do"
Jon Jones has never lost (that DQ doesn't count) and he's DOMINATED almost everyone he's fought -- but he ain't the G.O.A.T. ... so says Daniel Cormier.
DC -- who's fighting Stipe Miocic at UFC 241 this Saturday -- joined the guys on the "TMZ Sports" TV Show (airs weeknights on FS1) ... and was asked who he considers the greatest mixed martial artist ever.
The UFC heavyweight champ said himself -- along with Mighty Mouse and GSP -- were best ... but it was who DC said wasn't in the conversation that was more shocking.
"I really do believe when you break down the greatest fighters of all time, anyone with any accusation against their name should be omitted."
"I like Anderson. He's a great guy, great champion. Jones, a great fighter. But, any time you have anything attached to your name, I think you should be out. You're not supposed to do it that way," Cormier says.
"But, Georges St. Pierre, Demetrious Johnson, I think those guys along with myself should be considered the greatest fighters of all time."
