Tiger-DePaula immediately comes to mind, as well as Louis-Conn I. I'd also like to see the first Louis-Walcott fight.
I'd quite like to see the first Hagler Vs Finnegan fight All Level when Finnegan stopped by cuts, 8th Round as i recall, With Finnegan his face a mask of Blood winning the Last two rounds and appearing to possibly have the momentum to Join The Worm and Boogaloo... Amazingly they Put Kevin back in with Marvin Less than two monhts ? ( as i recall ) Old Marv couldnt put Tough and Skilled Kevin Down.. He later payed Kevin the Comp of being one of the Toughest Men he had ever fought.. If Only Kevin didnt Cut... and Didnt like Guinness Quite so Much..

I can't comment on the others but Witherspoon vs Wills 2 was on ESPN. I think I have it on an old beta tape somewhere. Witherspoon landed on of those looping overhand rights & got Wills out in 1.
