With so many intangibles in boxing the ref has a hard time doing his job, I mean the ref can only see things from certain angles and some low blows go unseen, Abraham, ward, dirrell, khan are all guilty as fuck for what they have done and fighters have been hurt in the long term because of it.
Perfect example is benn vs g man with the headbutt, ok he didn't butt him with want but he still did it and the ref did fuck all regardless of the "suspect" quality of the ref.
Also khan hit Peterson whilst he was down but Abraham got disqualified?? Wtf
