Is Floyd finally retired?

[Batman]

If Floyd was THE GREATEST as he claims 24/7/365 then why fight Hatton at 147 instead of 140? Why wait until Cotto has 2 losses to fight him? Why fight Shane Mosley in 2010? Why fight Oscar De la Hoya in 2007? Where's Kostya Tszyu on his record? I'm looking I don't see Kostya. Where is Paul Williams? Where's Margarito?

Wasn't Hatton already fighting at 147 when he fought Floyd?
