74 - I drew a massive mental block over really obvious ones. Got both Jack Dempseys but couldn't remember Manny Pacquiao's ****ing nickname!
One that totally stumped me was Kid Gavilan. My first reaction was 'wait...that wasn't his nickname?!'
91. And, somehow I missed Margario as well. I should have known that. The other ones I got wrong (Like Harry Wills) I genuinely had no idea. That was actually a lot of fun.
