As the Hawks' finished the final session of their camp at the University of Georgia Thursday, director of rehabilitation Mike Roncarati made his way around the gym, stopping for a few seconds with each player. The final player he approached was Kent Bazemore, who stepped away from a free throw competition to turn his back toward Roncarati, a member of the Hawks' newly reconstructed training staff. Roncarati reached between Bazemore's shoulder blades, slipped his hand inside a compartment sewn into a compression shirt, and plucked away an electronic device the size of a chicken nugget.
