Brett Brown is talking about practice. In the thick of an NBA season, practices can be a rare commodity, especially on an injury-stricken team shorthanded in healthy participants. Between games, travel days and the basic need to rest, the schedule doesn’t allow for many afternoons to run drills and scrimmages in the gym. But Brown wants to have more of those opportunities and balance them with the awareness of the team’s injury situations. “I think we need to get better individually,” Brown said Sunday after practice. “I think that we’re going to have to do a little bit more practice and be maybe a little less concerned always about load management. We are so mindful of sports science and the rhythm of the NBA calendar, you just need to work to improve. It’s a simple formula. “And we work. We try to work intelligently and not take tolls on their body all of the time. It’s especially been effective with just the mass injury we’ve had. So there’s a portion of what I’m saying that needs to be tempered with the reality of a schedule and a reality of a health. But we have to find ways to improve individually that will add up collectively and to the obvious areas that we need a little bit of growth.” The Sixers are in the midst of a season-high five-game skid, as they approach the next four games on the road (Knicks, Trail Blazers, Nuggets, Suns). It is no secret Joel Embiid is the key to their success, and while he did return Saturday after missing three games because of back tightness, he did not go participate in Sunday's practice. Embiid received treatment while the team went through their work.
