I think Gus vs Rumble is a 80/20 fight. Gus should take that one alot of times, due to his footwork, speed, cardio and boxing. If Gus beats Rumble I think he has a great chance this time against Jones. Even if Jones knows alot more about Gus second time around, there is one thing that makes the rematch tip in Gus favor. The fact that Jones boxing defence has not gotten any better. Even a short DC connected with some jabs and punches from range. Gus knows coming into the rematch that he can stuff alot of takedowns, this will make him open up his striking alot more. Him knowing what he can do now will make him push Jones alot more in a rematch. With pushing more I mean longer boxing combos, he did it a few times and Jones attacks was all gone. I see this as the biggest factor to Gus winning the fight. Jones has a bad defence when it comes to boxing, he freezes up, going straight back. Watch the first fight and pay attention to the times Gus put together some longer combos, you could also see it in the DC fight a few times. If Gus uses his footwork to cut angles and puts together longer combos he will win this rematch, I can't see Jones dealing with it. I said IF, I think this is at this time the only key to beating Jones, Gus has the tools. He just has to push his boxing alot more.
