Randy Couture is the current heavyweight UFC champion, how would he do against these fighters in a streetfight

i think he would fair well against quite a few of them considering that 3 or more are dead. yes i know you said "if in there prime"... foreman wouldn't stand a chance. andre was, huge yes, but incredibly slow. if carry ewles can take him, so can Couture. Oyama......we have skinny little guys from spain that fight bulls and win all the time. jimmy kim.......TKD....do i need to say more? ed parker, dead and randy bested liddell at least once (liddell does AKP). gracie...Couture knows the BJJ game well enough to have a chance. the thing is, that any of the guys have the same chance of beating any of the other guys in a street fight. it would all depend on who would was the smarter fighter and could exploit the other's weakness. Couture is a very intelligent fighter and has a knack for exploiting weaknesses. he's not called the "Natural" for nothing.
