Hey look, there's Boxingislife hating on Jones. Again.
Dude, we get it, Jones' boxing isn't very good, we don't need a wall of gifs reminding us. But besides the Gus fight (and the DC fight to a certain extent), Jones has gone through most of his fights relatively untouched. To have fought Shogun, Lyoto, Rampage, Vitor etc and come out the other side unscathed says you're doing something right defensively.
But as everyone's already said, GSP is the defensive king. He actually far more active offense wise than a lot of people give him credit for, but he was definitely risk averse. A pretty smart strategy to take in to a cage fight, IMO.
