This. Collin has plenty of say in where he re-signs. This was one of my thoughts that will be on the podcast tonight.
Yeah, generally I don't think nuking a player's value is great if you plan on re-signing him. He will have less value, but what are the chances of the player wanting to re-sign? If the Jazz thought Sexton was a big part of their future, they probably wouldn't be nuking his value in the first place.
So Sexton is likely to expire and leave....or we trade him. His value is probably not great right now, but it will never get better.
