You can do some things that help a little but it's not gonna change a lot. Training shot blocking will help, as well as OD and ID and stamina so it's not under 5 anymore. Then playing a slow pace and matching him up with a player that doens't draw many fouls can help too.
SB is arguably the most important skill, as a big with high ID but low SB Will contest many shots, but foul because his inability to properly block the shot.
