Alexander Gustafsson can beat Jon Jones. Not only can he do it, he very nearly did. What do you think he could do differently in a rematch to ensure the victory? For me, the main things would be:
Conserving energy. Gustafsson wasted a lot of energy with his excessive movement, throwing the wrong kicks and trying to wrestle too much after his initial success. Had he been fresher in the final rounds I really think he would have won the fight.
Body shots. He started using these WAY too late in the fight. Had he used them earlier, Jones would have worn down significantly more by the end of the fight. No one has gone to the body with commitment against Jones and I doubt his defense is particularly good.
Leg kicks. Jones uses the same defense almost every time he is attacked; fingers in the eyes as he backs up and circles. There isn't really the threat of a counter, so Gustafsson could take Shogun's gameplan against Machida and use it against Jones. Kick his legs out as he tries to move out of range to punish him for that defense. If he keeps using it, you keep hurting his legs. If he stops, you keep him in boxing range where he is CLEARLY uncomfortable and has poor defense.
Slipping to his left. One thing that really stuck out to me by the fourth round was that as Gustafsson tires, he only puts his weight on his right hip. As a result, he was always jabbing and slipping to that same side over and over. When Jones picked up on that, he landed a spinning elbow that very nearly led to a finish. The ability to slip both ways even (especially) when tired is absolutely vital. Gustafsson didn't have the energy to keep moving his feet, so he got caught stuck on that hip. This is a big problem that needs to be fixed.
Cross Counter: Jones relies too much on just putting his lead arm in the opponent's face. Slipping inside that and throwing a right over the top could go a long way towards knocking him out, or at least just beating him up.
What do you guys think he needs to do if they fight again?
