So your not going to build a contender with a gobert and picks in the late teens in the next 4 years.
If you keep him you're looking at having a mediocre team at best and starting the rebuild in 4 years instead of now. Basketball is a team sport.
You rebuild around Gobert. Let Hill go. Let Ingles go. Trade Burks. Trade Favors. Basically everything goes except Gobert, Exum, Hood, Lyles and your draft picks. Gobert is a 24 year old superstar. Why trade him to search for someone you hope can become as good as him? Pointless.
