I'v got quite a few i'm trying to beat Tyson on G.O.A.T. It's hard i'm up for the challenge I keep getting to round 6 of 10 and get knocked out. lol.

Go to gameplay settings,
Up to max: Referee damage awareness, Boxer physical damage

Put the rest to lowest and spam straights, within a fews round the ref will stop it on cuts. I did this for Tyson and Ali.
