Jones is still dangerous in little bursts and theres no way i can see Joe knocking him out either (He simply doesn't hit like he used to be able to).
Joe's workrate alone should see him through to a big points win but Jones is still dangerous,i don't care what anyone says about age etc.
If we see a tuned up and focussed Jones then anything is possible.
I think Joe will have to box brilliantly and this could turn into a war very early on.
