We need to start giving some of these modern fighters a bit more respect and realise that it really isn't cool to take punishment.
Sports science is way advanced now and the methods used in todays game in boxing including nutrition has moved forward from yesterday.
We all like to watch a good scrap but If I was a pro boxer I would prefer to be the smart one that dishes out the punishment and avoids and frustrates the hell out of any opponent by making them miss.
And we know the same tired excuse.."He was running"
In other words, you just weren't good enough to beat him.
