I just think the rest of the season smells like a buyer's market. None of the true contenders have the type of debilitating injury issues or holes in their rosters where they'd be desperate to bring in guys like Clarkson, Olynyk or Vando - let alone Conley. And I don't see most of the middle class teams trying to get stronger at the last minute for a possibly fruitless playoff run that would only kill their draft positioning.
My hunch is that Clarkson isn't gonna find the bag he's looking for out there, there will be absolutely zero market for Vando and Conley, and Olynyk will draw some interest but not the type where it would make any sense to trade him.
It's not as simple as "Let's sell off our veterans".
