From what I'm seeing on Comcast and reading on Boston.com, Rondo looks good:
Rajon Rondo walked onto the Staples Center floor at 6:27 p.m., EDT. He had both ankles taped, his injured left ankle no more heavily wrapped than his right.
The Celtics point guard did some light shooting. He got good elevation on his jump shot. He was relaxed and joked with his ball boys.
Sitting right next to the court, I saw no hitches in Rondo's warm-up. He looked good.
