Unless Gustafsson tighten up his boxing defense he will lose. While he's got a great chin for now, taking too many shots will eventually crack it. He's got a while to go before he can bring it to Jones. Taking punches to the face is one thing but he gets elbowed and cut, there's a high chance he might be blind from the blood in his eye and then he will get picked apart. What I'm really trying to say here is he needs to be a more conservative striker and not just trade punches because someone will eventually catch him.
