Last night before the last regular season game of the year, we got a rather alarming update. 76ers’ GM Elton Brand seemed to hesitate when discussing his team’s best player, Joel Embiid’s health and readiness for the playoffs. When pressed about the issue after the game, coach Brett Brown abruptly cut off the line of questions and suggested the team would give a “fair” update on Joel’s health. Although Brand said he’s optimistic Embiid will play and Brown made clear he expects to have his starters for Saturday’s game against Brooklyn, that this isn’t a given (after how much time the big man has had to rest his knee down the stretch of the season) is a major concern.
