IMO, we have to do whatever it takes to get in the playoffs next season. No high end free agent will go to a lottery team. Bringing in Jason Kidd, among other moves, will get us to the playoffs.
Obviously Walsh is confident he can move Curry and/or Jeffries. Curry is likely headed to the Rockets. They don't have a lot of other options. Jeffries shouldn't be THAT hard to move. Couple him with Nate to a team like the Kings, should be enough.
