I don't really get why this is such an amazing deal?
The 76ers get one draft pick that should be top 10, but is top 10 protected. No help.
The 76ers get to swap their picks for Sacramento's picks, which most likely never happens because the sixers picks probably be higher (if they are worse, it's not likely to be by much).
The 76ers (who are rebuilding remember, hence are trying to lose) get Thompson and Landry. They risk making the 76ers actually win a couple of more games (hence hurting their tanking efforts) and add a combined $13M to their salary cap at the same time.
(76ers get Stauskas who is kinda useless right now as both a player and an asset - he generates nearly zero interest to any team.
For Sacramento it gives them cap space to sign Rondo - a guy who is a notorious hot head, who is known for being hard to get along with, who hates losing, and who doesn't respect authority. Man, that's going to go down great in Sacramento alongside Cousins and in THAT management structure.
I just don't see how either team is helped long term by this trade.
