Should Heavyweights have to make a certain weight

[L.Ellerbe]

I mean over the last few years we have seen heavyweights get big opportunities and ruin them by coming in obese...kirk johnson sam peter rahman and toney spring to mind

what if each individual heavyweight had to come in at a certain weigt ...for example if the organisations doctors performed tests on the fighters and said that for this particular fighter he shouldnt be allowed to weigh no more than say 240 for this particular fight

d you guys think that could work at all
