I think that a top 3 pick would have made it more likely that Rondo be traded, because the team may have been tempted to build around Embiid, Wiggins or Parker. (Parker may have been the exception in that in terms of scoring, his game is more NBA ready.)
The fact that we got the 6th pick and the dropoff after 1-4 (including Exum) is so steep makes us more likely to trade the pick for immediate help for Rondo. (someone like a Melo or a Love), unless Danny is truly masking his lust for someone in that second tier of players.
Unless Danny gets a Godfather offer, I think Rondo stays and gets help.
