Embiid has a weight issue. Although the Sixers wouldn't disclose his weight, a source said he's close to 300 pounds after being 250 pounds at Kansas last season.
His work ethic is being questioned by some inside the organization.
The Sixers are trying to address the added weight. Embiid, however, hasn't always been a willing workout participant, according to sources. He's even blown off conditioning drills, one source added.
An altercation with Davis during the West Coast trip, coupled with Brown's wanting him to be in "more of a structured, stable environment," pushed the Sixers to send him home, the sources said.
