Rumble needs to go downstairs. Jon has a chin, and most likely has better cardio. Rumble needs to go to the body early and often to remove Jon's gas tank and to impede his movement.
Jon needs to treat Rumble like a younger, faster version of Page and stay far away from the nuclear warheads attached to his wrists. Pick him apart until he gasses then go in for the kill.
or, short verson: Rumble: Body-shots / Jones: sweeps to the knee and long jabs.
