You fellas have already covered all bases.

Immediately thought of Edison Pantera Miranda, and there's still a bit of a question about David Haye. Haye's TKO loss a few years ago was mostly because he ran out of gas because he wasn't training properly looking past the old journeyman Carl Thompson; Haye almost had Thompson out of there.
Haye's learned from that mistake and always comes in in top shape now.

Also, the 6'3" Haye has really struggled to make 200 lbs the last few years.
When a man stops draining himself through dehydration and comes in instead at his natural fighting weight, he's often able to take a shot better.
At 140 lbs, Cotto's chin seemed questionable, but look how much punishment Cotto was able to take at 147.

I loved watching Julian Jackson, most of his fights happened on regular network televison.

For a real dangerous old-timer with deadly 1 punch power coupled with a glass jaw: Bob Satterfield.
