Seems like Lights Out was eating too many burgers when he was campaigning at heavyweight. If you could get him to disciplined (perhaps by promising him lifetime of free burgers post retirement if he stayed in shape during his career), what would his ideal heavyweight weight be? He campaigned pretty decently at heavy. I think 205-210 lbs would be ideal. He would have enough punch resistance and punching power at this weight while also having a highish work rate to succeed. I could see him beating anyone from 2003-06 except for the Klit brothers if he stayed in shape.
James could have been the overweight champion of the world. He went on the 14-day diet and all he lost was 2 weeks.
Realistically being born in the older era when Heavyweights were Cruiserweight sized would be his ideal Heavyweight weight.
