Suitors for Kyrie imho:
Clippers have wanted a PG.  But they have nothing to sell to the Nets other than Kennard, Morris, Covington, Powell, Mann, Batum, and Wall.  Of those, I can't imagine Brooklyn really wants more than Mann.  The rest are all contract filler players that don't help the nets that much.  I mean, Morris, Mann, Covington, and Kennard for Kyrie?  It works on trade machine, but it sucks.  Clippers get their PG but lose Mann and their entire switchable lineup strategy for a Kyrie rental.  Doubt it.    
Mavericks want someone next to Luka, but do they want another PG?  It has been a trend.  Hardaway, Wood, and Green for Kyrie works.  But if I am Brooklyn, it's pretty meh.  
Lakers could swap Kyrie and a minimum contract for Westbrook.  But does Durant really want another round with Westbrook?  I doubt it.  
Would the Knicks do RJ Barrett, Fournier, and Reddish (two trash players/contracts + their current star) for Kyrie?  Doubt it.  
Toronto could facilitate a trade with say, FVV + Boucher for Kyrie.  But why?  It's a rental.  
Honestly, Conley, Sexton, Vanderbilt, Olynyk, Beasley... They are more attractive than alternatives.  
Man... this is just getting my hopes up.
