End of an Era. Penn will go down as a great, one of the first to ever be champion in two weight classes, having defeated some other greats as is required. However the last few years of his career and life have been a tailspin. Like Anderson Silva, he faces some degree of ignominy rather than celebration. The UFC usually releases guys so they can fight elsewhere. There will be plenty of vultures waiting to pick his bones. Hopefully he makes good choices.
