They won't give up #8. I know it's silly because there is hardly any difference between that and 10 but they will very likely have one of the star point guards available at 8 (it won't be Fultz or Ball or even Smith but could be Fox and should be Ntilikina) and they must want that. One of Monk, Isaac, Smith and Fox will have to be available there, assuming Fultz, Ball, Tatum and Jackson go in top 5 almost for sure.
This also means we have no real reason to move that high. We don't need a backcourt player, and unless we see opportunity to get Isaac (Tatum or Jackson are pipedreams), we won't be looking at top 10 at all.
I got a feeling Sacramento will end up with a no. 5 pick though. They will be drawn in top 3 but will have to surrender the pick to 76ers who won't be in top 3 (swap rights already belong to Philadelphia, correct?). Lakers will get pushed out of top 3 so Phila will be picking 1-3 and then 4th and then Kings get Philadelphia's pick which is now 4 but will be pushed to 5 as Lakers drop. Or maybe even both Sacramento and Philadelphia are top 3.
