Chauncy Billups was put through the ringer over his allegations before the Blazers took him on. If the Spurs are interested they will so the same. We aren’t exactly a desirable destination these days.
Any team interested will have to do their due diligence. If he’s largely innocent outside of a breach of contract he will rebound. Additionally, he is probably already lawyered up to get an exit package from the Celts and/or have others sign NDA’s.
All this won’t happen over night. He has some stink on him so might take a lil time to rebound even if it was all consensual.
