If you adhere to the adage that 'there is no such thing as bad publicity,' which WME seems to, then yeah, bring back that coked out roid monkey of a train wreck.
If you think the UFC should stop being a fn soap opera full of adult children and PED scandals, then no, move on and actually promote people to fill that division.
As an aside, have people noticed that the older the division is to the UFC, like LHW and HW, the older the fighters who occupy the top 10 are? People around here seem to shit on the manlets and the ladies, but at least those arent divisions filled with 40 year olds past their prime.
