What prime? He came up in 1997 when the fighters he beat were hopeless on the ground (legends like Paul Varelans, Moti Horenstein, Greg Stott, Dwayne Cason). He fought 3 chumps in 1998 ending off with Hugo Duarte, the guy Tank Abbott destroyed in about 40 seconds. Garbage fighters with no takedown defence and ground game off their backs. By 1999 he was exposed by Igor V. as a one dimension wrestler and pretty much got destroyed by every decent fighter afterwards. What prime? lol. Sure he did ok controlling guys on the mat at ADCC (hint, they don't hit back there). How many brillant subs did he do in MMA? The guys is/was a garbage steriod machine.
His prime when he was ranked number 1. regardless of whether his opponents were cans or not. Kerr was a UFC champion and was destroying everyone they put in front of him. I'm not saying Kerr was a great fighter overall, just simply pointing out that he wasnt 1 dimensonal. Had almost half his MMA wins via Submission. Kimura was one of his favorites. I know you don't know much about MMA or sub grappling but believe it or not to enter ADCC and win you must have vast knowledge or submission and submission defence. Jeff Monson has very few wins via sub but is a BJJ black belt. I guess he is one dimensonal too right?
You are like the posters on Sherdog who forget that sprawls are also a wrestling move too, and to be well rounded you have to be aware of offensive and defensive measures.
I cant believe I'm wasting my time arguing MMA stuff with a guy who think you can win ADCC (the superbowl of submission grappling) and be a submission novice "because Kerr didnt have any brilliant subs in MMA". Right only 7 of his 15 wins came from submissions.
