For me I see it as a straight forward 3-0 to the UK

Roy Jones is so shot its a joke and even a Calzaghe with badly damaded, brittle hands will force a stoppage. Jones doesn't have the legs to get out of the way and Calzaghe has superb handspeed and timing.
Even though Joe is faded himself - this is a mismatch and a nice fat retirement cheque for Joe.

Haye will KO Barrett as soon as he catches him flush. Haye is faster and bigger and Barrett while still a decent heavy, has often relied on his sound boxing and decentish movement to keep him away from trouble. He won't be able to escape from the lightning quick Haye.

Hatton should beat Malignaggi in an uneventful affair. Malignaggi will move and hold - Hatton will stalk and hit in the holds. I think Rickys forward motion will wear down Malignaggi to a fair if unspectacular points win.
