This won't happen and I hope it doesn't. Dragic already said he plans to opt out after this year to become an unrestricted free agent. He also said he will quicky re-sign with the Suns (though who knows how true that is).
Either way, I don't want to trade anybody for a half season rental of Dragic. I think the Milwaukee Bucks traded Tobias Harris for half a season of JJ Redick, and I'm sure they regret that.
This, no reason to trade for Dragic. A half season rental and a worse draft pick is all we would get. If we want him try to go after him in FA but he is going to a contender or back with the Suns IMO.
