Not only does he talk smack then get fed often and hard, he's the only fighter I've ever seen lose with no grace! When he fought Sakuraba he whined to the refs and left, same with the Tito fight. Others may have done it, but have only seen him do it! Sometimes I think he believes he's still working for Vinny Mac.
A classless has been/never really was who needs to call it a career and after seeing him "coach", forget about that as a career as well.
His legendary status is the result of UFC needing a "idol" to promote the sport. Nothing more, nothing less! Ken my boy, look at the clock 14:59 and counting!
