I wonder whether some version of the following could be done?
Cs trade: Smart, Richardson, Nesmith, 2 seconds
Cs receive: Brunson, Hield
Mavs trade: Brunson, Powell
Mavs receive: Smart, Len (or James), 2nd round pick
Kings trade: Hield, Len (or James)
Kings receive: Richardson, Powell, Nesmith, 2nd round pick
For this deal to work, the Kings have to see Nesmith as a talented player glued to the bench behind veterans (not a guy who can’t crack the rotation). I’m also presuming the Cs can get a top-half-of-the-2nd-round-pick for Schroder, then send it to the Kings in the deal at 2:59pm on Feb 10th.
