I think Butler ends up being available this year, and Danny ends up pouncing on him then.
Cousins could very well end up available, too, especially because once again it's hard to really see them challenging for a playoff spot. If Sacramento isn't really in the playoff race at the deadline, I expect him to get moved.
Though this all could be preceded by him trading for Love, who I think will have to get dealt before the season, or taking a chance on trading for Westbrook, who I also feel confident will be on another team before the season starts.
