"Kevin looks good, he's in here working out every day," Ainge said today from the team's practice facility in Waltham. "He's doing his training but he's not playing fullcourt basketball, yet.We're taking it as slow and as cautious as we can with him. He's anxious and he has a ton of energy, but I think he gets it. We don't have bodyguards on him to keep him from working too hard. He's on the program with the staff. We don't have timetables on this. We are going week to week and we'll make a decision on where he is."
