Lacy was being hyped as a SMW "Tyson" before Joe owned him. Go to boxingscene and look at their writers and DWFs opinions on why Joe would get owned and then just like every other fighter Joe beat they suddenly became "washed up, past prime, overrated, bums ETC" afterward. If Joe were ever to lose no matter how old he was they all would've been gloating about him being a protected hype job that was never any good.
Calzaghe was a joy to watch but he was clearly starting to decline and lose the motivation to stay on top so he got out at the perfect time, undefeated and with dominating victories over his affletic contemporaries, Hopkins and Jones. The big 4 (MW-LHW) during Calzaghe's reign were himself, Hopkins, Jones and Toney and Joe was clearly the best which is why the DWFs HATE him so much.
