I want to know who you think is the very best not very good fighter. And I want to know who you think is the worst all time great. Some suggestions for Goat Can: Keith Jardine, hat tip @Dead Kennedy Forrest Griffin, I love the guy, but he's such an over achiever. Darren Elkins. I find myself thinking he's a can because he takes an ass-whooping nearly every fight. But then he wins those fights, and that's pretty impressive. Suggestions for Can of the GOATs: BJ Penn: an all time great for sure in my book. But not a great all time great. Brock Lesnar. Ronda Rousey. Never went to a decision. Either won or lost spectacularly. I'm sure you all can come up with better candidates.
