Even if they are not fighting for sure both of them are well trained since we know Deron is former NBA player and for sure he used to trained everyday since that is what his routine even since before and Paul is already trained fighter so its expected for them to have this training but this will matter only on how they discipline their selves. Also I think age will play a huge role here knowing William is already at his 30's.
Good point, there's a daily routine to maintain his physical body, but he needed to add more workouts since boxing is far different
from basketball and the trainings to increase your stamina needs some extras, though it's just an exhibition. But I'm sure both fighters will extend some effort to make sure that they will give the fans some entertainment.
Who knows if fans see the competitiveness between Williams and whoever the fighter he will face, another set of exhibition
will be rewarded for them.
Just saying the possibilities, it's still on the promoters side to decide if they want to pursue giving another opportunity to
Showcase their skills.
