Difference between random drug test & catchweight?

[kalandagan]

When Floyd's camp asked for random blood testing isn't it just like Roach asking for catchweight?

[Dirk Diggler UK]

Catchweight fights are nothing new

i dont know what the big deal is about olympic style testing....arthur abraham has it done in every fight.....floyd didnt invent this

Catchweights have an impact on the actual fight. Random drug testing shouldn't (of course unless one fighter is using something).
