I don't consider Jones in the running for GOAT yet either but I think the difference is that you can't find a guy who people think can beat him so it gets thrown out there prematurely. It's different with the LWs because you can't look at one of them and say, I don't see how anyone can beat this guy.
There may never be a GOAT at LW and there doesn't really need to be. It seems like everybody is jumping on this GOAT bandwagon lately and I'm not sure why. The only weight class you can look at and say we may be seeing the best ever is MW.
