The GOAT somes are quite easy really, just create a boxer with 100 for each hand and stamina, then just use the remaining points on movement and heart/chin etc. Against Tyson you need to box on the outside and keep out of his reach, and with Ali you do the opposite, get right up close and try and corner him and just go nuts on him, but watch for counters.
You can mess with the sliders aswell if you wish, but I feel thats rather cheap imo
