When George came back from a similar injury, he played 15 minutes a game in 6 games with 9 points, 4 rebounds, 1 assist, and 1 steal on 37, 41, 73 shooting percentages.
Expect a similar struggle. Getting feel and playing speed back takes time. That being said, I'd love to have him work his way back on the court. He'd still give us positive help.
