Right now, the Atlanta Hawks practice in a no-frills gym inside Phillips Arena, not far from the arena’s main court. As practice facilities go, it’s outdated. No high-tech video room, hydrotherapy pools or high-end kitchen. No massage room or players’ lounge with pop-a-shot and HDTVs. Just one full-sized court. Some big-time college basketball programs have nicer practice facilities and more amenities. That’s about to change.
