Good time for British level boxing where the Heavyweight Brits got in the ring with each other with Audley, Danny Williams, Sprott, Matt Skelton, Scott Gammer, Martin Rogan, John McDermott along with a young Tyson Fury. Not much between them all during this period but I think Audley could stop Big Bad John if he let his hands go.
To be fair i remember that fight and if you were gonna bet the odds were such that there was no point in betting on Haye
Don't forget David Price. Although I'm not sure he fought many of the guys you've listed? Perhaps he was just after.
Del Boy, Price and Sexton arrived a couple of years later but in the ring with some on the list as well at the end of their careers.
