Celtics coach Doc Rivers says that Kevin Garnett is still in the process of recovering from last season's knee injury.

At times, Garnett lacks explosiveness and he went 5-for-13 from the floor in Friday night's loss to the Magic.

"No he's not (finishing)," Rivers said. "One day he's explosive, one day he's not, one day he's healthy, one day he's not, and that's just gonna take time. Coming into the year, obviously you would want him to be explosive if you could pick tonight. Tomorrow we don't need you.

"But you could see that today," he said Friday night. "It takes time. Some days you have legs, some days you don't. It's your back. It doesn't matter what the injury is, almost. That's just how it works."
