The following is my guess at trade packages each team could plausibly offer involving the 3rd pick. Trades in Green are deal I really like for the Celtics.
Nets, #3 + KO for Lopez? not likely but I guess the possitive is it would cost Nets wins next year
Knicks, #3 + Smart for Anthony? I'm not a fan of trading for Anthony but deal could makes sense
76ers, #3 (Dunn) for Okafor? This makes alot of sense for both teams
Raptors, #3 for Valanciunas? Raptors could then draft Murray to replace Derozen if he leaves and then resign Biyombo
Bulls, #3 + AB/Smart for Butler? Bulls get younger and start building for the future.
Cavs, #3 + AB for Love? not likely the way the Cavs are playing but lets see how the rest of playoffs go.
Hawks, #3 + KO+ #16 + #23 for Milsap and Korver? This only makes any sense if ATL know they will loose Horford and want to go into a rebuild. Murray and Schroeder could make for a nice front court and they can hope to find a center (Zizic) at #16.
Hornets, none
Heat, none
Magic, none
Wizards,none
Pistons,none
Pacers, cant see Paul George going anywhere none
Bucks, #3 + #16 + #23 for Monroe and #10. The Bucks draft Murray to play PG and add shooting to their young core and depth with additional 1sts. Cs upgrade Sully with Monroe and still have a lotto pick to take a shot at a high upside big (Ellenson, Chriss, Labissiere)
Warriors, none
Clippers, #3 + Crowder + #16 + #23 for Griffin. Leaves the Cs with a major whole at SF and not sure its enough for the clippers to make a deal.
Lakers, #3 for Randle and a future protected 1st? If the lakers end up with Simmons Randle no longer fits. This trade allows then to add a young player who better fits next to simmons. For the Cs Randle is an upgrade over Sully.
Suns, #3 + #16 for #4 + #13? if the player the Cs like isnt the same as the guy the suns want this is a simple trade to move the #16 up a few spots
Kings, #3 + KO + #16 for WCS + #8? Kings would be able to add a shooter in Murray with the pick and add a shooting big in KO to better fit next to Cousins. Cs add defensive anchor and still have a chance for Hield or Brown at #8.
Mavs, none
Rockets, none
Grizzlies, #3 for M Gasol? this is a rebuild move for the Grizz and a super gamble (to big of a gamble) for the Cs
Pelicans, none unless they want to trade future picks to move up
Spurs, none
Nuggets, #3 + #31 for #7 + Faried? Denver moves up to get Murray to pair with Mudiay, the Cs move down and still have a shot at Hield while replacing Sully with Faried.
T-Wolves, #3 + #16 + #23 for #5 and Dieng? This only works if the T-Wolves are locked into one player (Murray) in the draft. Dieng would be a nice upgrade over Amir for the Cs and Hield would fit nicely at the #5.
Thunder, #3 + AB for Ibaka, scary trade given that Ibaka is going into a contract year but his under used abilitys could be a dynamic change for the Cs.
Blazers, none
Jazz, none
