Zion is reportedly making progress on returning, but slowly. He was just cleared for one-on-one drills. There's a long way between that and playing in an NBA game.
There's no way not to worry about Zion's foot-and-knee injury history that dates back to high school, and his size, particularly given the force with which he plays, only heightens that concern.
Williamson is listed at 284 pounds, the same weight he was listed at last season, but, per Bleacher Report's Jake Fischer, he is believed to have reached north of 300 pounds as recent as the preseason.
ESPN's Brian Windhorst and Andrew Lopez, that includes changing their "culinary practices" -- i.e. keeping the junk out of the cupboard.
From ESPN:
The Pelicans have poured resources, time and energy to protect Williamson's health. They have changed members of the staff and even changed some of their culinary practices in an attempt to support him. They have talked with him about protecting his body from extra hits.
There's only so much the Pelicans can do. Zion is a grown man who is going to ultimately make his own decisions as it pertains to what and how much he eats.
