I could definitely be wrong but it seems like they've turned him into someone that's way too methodical in his striking. Against Santos he kept cutting him off only to use a spinning back kick to the body (and miss) and have to chase him again. Against Reyes he only did that maybe once, but he still chased just to throw too few strikes or get pushed back by Reyes' punches. For some reason Jones seems to have abandoned his clinch game which was deadly and you can see so in his fight against Glover where he took Glover to, arguably, his best position and beat him up for 5 rounds. The rhythm of his strikes and setting them up used to be much more dynamic as well, potentially thrown off a bit by not being able to palm people on the forehead anymore, but I doubt that's the entirety of the problem. On top of these, even his wrestling is effected by his slow, methodical, new pace. Against Reyes, whenever he shot it was completely raw; it was never mixed in with anything. Jones used to throw multiple shots to the head to make them cover and then change levels. Feels like they've turned him into a robot that is able to do only some of the right stuff and his talent and chin are carrying him to these close decision victories.
