I trust literally nothing I read about trades, picks and FA's unless there is a named legit source but I will say this that if a team has access to either very seriously accurate scouting or a crystal ball, and the Kings org clearly has neither, then this could be an excellent draft to trade down. History tealls us that there are likely a few guys outside the top 3 that will turn out to be really great players and a couple disapointments in the top 5... the trick always is figuring out which is which. With the number two pick the Kings should not even thing of getting cute. You drew a great hand, play it straight up. But If I am Dallas and I am solid on two or three guys I think will be on board farther down, then I would take the risk to amass more young prospects and try to pull a rabit out of the hat.
This is honestly what Vlade did the last two drafts with mixed results. Last year he flipped #10 Collins for Giels and JJ (jury still out) and in 2016 when he flipped #8 Chriss for Boggie, Skal and Pappa G (Looks like a win). To be clear I am NOT saying the Kings should pull this trick again, just the opposite. It's time to use that #2 for as a sure a deal as you ever get tin the draft. But If I am Dallas and I am starting from gound zero I want losts of prospects, I take risks and search for hidden gems this year.
