Philadelphia has been connected to trade scenarios of all kinds up to this point, but a league source said Thursday that a trade down was unlikely as of this juncture. The Sixers are believed to have four players they’re focused on at the top of their draft board, sources say, and thus would feel less comfortable trading out of the top four and missing out on one of their priority targets. The Sixers would probably need to be bowled over with an offer to trade further back than the Hornets’ slot at No. 4.
