Dan Severn. 100-18-7 career
Fedor Emelianko went nearly 10 yrs without a loss
Don Frye, frank shamrock, pat militich, sakuraba, belfort, rutten, aldo, Penn..... List goes on and on. Anderson Silva is. Bad dude no doubt. He wouldn't stand a chance against severn,wanderlei Silva or some of the old school guys. But there is no way to actually answer any of it so guess it don't matter really I just think the old school guys were better than the guys today. Meaner for sure. I know tito was a POS but he had a Hell of a run for a short while. No he isn't in the running for best of all time by no means
