Honestly, you can’t prepare for Shakur. Dude is content with being a “boxer” and not a “fighter”.
To win off points you have to be extremely skilled with cat like reflexes, great visual acuity to see punches and a high Boxing IQ. Plus the boxing gods gifted him with long monkey arms. Giving him crazy range with risk of being hit.
Like Floyd did, he frustrates boxers because which is funny to watch.
