I'm a big fan of GGG, I think he's great. But I don't think history will be very kind to him. People will say he was the best of a bad bunch of MW's and he will get avoided by Canelo and Cotto. He won't beat Ward at SMW, because he's not big enough strong enough or good enough. That's no disgrace, Ward could be the best SMW There's ever been , although he's been nowhere near active enough to prove that.
So if he does go up to SMW after Ward has gone to LHW and beat them all, again people will say, "he wouldn't have beat Ward" or "again the best of a bad bunch" this is why he was desperate to fight Froch, because people would've given him credit for that , although I believe Froch was overrated (mainly by himself!)
And let's not forget , he's what 32? 33? Time is running out, it could all change overnight. Not everyone can compete at the top level way into their Thirties like Floyd can.
