Nahhh, I going to do what they did in the hurrican movie, by having Mendoza beat Jackson all across the ring, only to get robbed by the scorecards because the judges were anti jews or something.
Mendoza was at a loss at what to do with Johnson's straight punching, couldn't figure how to defend against that style of punching, despite all his cleverness.
mendoza wrote his Memoir in 1815. you could start with him writing at a table flashback to his career humphries, jackson, and on bring it back to real time - he arises from the table and heads for the ring, another bout at age 51
