This thread needs a title change
It says "Who had a more humiliating end to their career". As far as I know, BJs career has not ended. If someone says "it will end", it is only an assumption. BJ still has a lot in front of him and doesnt fall into the same category as Chuck.
Having said that, BJ need to move to his natural weight class. As already pointed out by several folks here, there are plenty of challenges for him at LW. At this time, even at LW, he would not be a top 5. There are several folks there who can beat him easily. He has to go down, concentrate on his cardio, get in shape, rededicate himself. If he is lazy enough not to do that, it is better he take up commentary or something and retire. I dont want to see him coach an young fighter and infuse him with his laziness.
