I agree with Jones' wrestling game also diminishing. Everyone points out that he's slower, but they mostly look at his striking, it isn't just his striking, it's his wrestling as well. Like you said, he isn't as explosive anymore and his takedowns are easier to defend now. We saw it against a one legged Santos and against Reyes for the most part, yes he got him down, but that was a fatigued Reyes who has never been in a 5 round fight, and he was taken down in the 4th, but popped right back up. Izzy has better cardio, manages distance better, and uses his hips real well to avoid takedowns.
