Should Bernard and/or calzaghe retire?

[FRKO]

I can't decide, based on last night's performance, if Joe is losing his edge or not. Hopkins' style makes everyone look messy and sloppy, it's such a hard style to deal with, but I have a feeling Joe is on the downward slope now. It's hard to tell. Both of them should retire, IMO. I think Calzaghe's hands are finished.
