Well first off,
@Scalma's question was how many picks would they have to give us to take Batum so I was answering that I would be fine with their pick this year as the only one if they took Turner back plus filler. You are coming in asking a completely different question.
If I'm the Blazers I would still accept the pick with top-5 protection this season. Like I said previously the Hornets aren't going to finish worse than 6th or better than 17th. With protecting it top-5 they keep it if they get lucky or don't if they stay where they are at. I think that is more than fair for taking on as much money for Batum as that would end up being.
If I'm the Hornets (or frankly any team that isn't a contender) I would almost never attach a pick just to dump salary. The only exception to that would be if my boss told me I had to or if doing so was because I had another move lined up that I needed the money for. These types of trades happen all the time though so obviously some teams are in fact willing to salary dump with picks (just not unprotected anymore). Those are the teams I'd be constantly trying to take advantage of and if the Hornets are desperate to move Batum they almost certainly have to give up something good to do so.
