This sucks. Juniors don't always come back from ACL's because it just isn't worth it for them. He won't get a RS for this year, so he has one year left. If he isn't going to be ready to play in November, he isn't going to come back next year for half a season. We probably won't see him again on the court until November 2021, if he comes back at all. He will be 22 by that point.
If Polley doesn't think he will play in the League and doesn't want to go overseas, this may be the end of the line for him. I wish him the best in whatever he decides to do. He is a hustler and a class act.
