What's the biggest win a current champion could get?

[Masturbin]

Usman beating Whittaker (If Izzy losses to him) would be a great win.
It's an horrible style match up for him if he's able to overcome it it's a great win.
Imo 170 is stale and there's not much for Usman there

 

[Jarvan]

Adesanya beating Jones
Rose beating Valentina
Jan beating Jones

I could see izzy and jan beating jones

Rose is legit, but Valentina is Queen

 

[613]

Jones hasn't looked great in a while, but he is still clearly by far the biggest win in mma

 

[loisestrad]

Anyone saying that Jones isn't the biggest win, is straight up lying.

That's just how it is.

Usman v. GSP would be the biggest for a fighters legacy, never gonna happen though
