Toney would have been in a phone-booth all night so GGG might have been able to manipulate Toney's hands enough to land (or as misdirection to land) more often that you think, but admittedly that's a bit of a fanciful thought.

Kalambay I honestly haven't seen fight enough to know eitherway.

Hopkins and MacCallum are ATG so it's far too early to say but seriously doubt GGG would beat a prime version of either of those. McCallum wasn't 100% consistent but I'm not giving GGG an inch on that one.

Jones, no chance. Would be hilarious to watch - For a guy who uses his eyes as defence, with reflexes as good as they were, GGG would be utterly bamboozled.
