Holyfield vs Akinwande, which was scheduled for June 1998 - Akinwande didn't deserve another title shot after that pathetic performance against Lennox Lewis Lewis vs Tyson II - it would have been an AWFUL mismatch and absolutely needless one Holyfield vs Povetkin in December of 2011. Yes, Povetkin's promoters wanted that fight badly, but Holyfield probably commanded too much money so he fought Cedrick Boswell instead Andy Ruiz vs Michael Grant in 2015 or 2016 (don't remember when exactly) - Commission didn't allow Grant to fight Ruiz and it was absolutely right decision. It might have ended really bad, had they allowed him to fight Ruiz. That version of Grant was brutally knocked out by Krszyshtof Zimnoch
No doubt. But there were 5 to 6 other fighters at 135/130 that would have beaten Sal had he fought them.
When Ike Ibeabuci was released, there was talk of a comeback fight with (I think?) Ruiz, that would've been bad, but not as bad as Grant wanting to fight Dillian Whyte in 2016.
I think the general belief is that Mays was indeed that good maybe three or four years before and was well into his alcohol related health problems and fading fast by the time he fought Sanders. After the draw with Sanders, you can see that his management really scaled down his opposition while they tried to get him healthy. I heard that he was so sick at the time of his loss to nobody Matthew Lewis that he was told any future fights could be fatal to him as his liver was so damaged. His past rep at Kronk would've made a Hagler fight at least more appealing than fighting the likes of Caveman Lee or Mickey Goodwin. Hagler could've done serious damage to Mays. (I wouldn't sleep on Ted Sanders, who is a fascinating fighter who beat and went neck and neck with really good fighters regularly. He starched Alex Ramos right around this time. )
