At the risk of hi-jacking a thread, I don't think our plan is to trade down. I must admit that I am injecting a lot of "me" into that statement. I think you always go for quality, BPA, or whatever you want to call it. No matter how clever you work the trade, the over all skill of the team level drops by trading down. Get the skill and fight, scratch, and cheat to keep the skill. There could be a super star or two in the top 5 and trading down means we don't think we need a super star.
It is interesting who we have worked out now that Sacre has left. Maybe I have forgotten someone of the 2nd tier but Drummond, Henson, Zeller, and Sacre have been worked out in pretty short order. AND .... none other of the top 5. No, I don't think it means we aren't going to resign JT because I think that would be a major mistake but it shows we want a big guy and maybe a little of it is for insurance in case we can't resign JT because of money. (Damn Maloofs!) More likely, it is a solid rebuke of small ball.
Although I am 100% a follower of the "we need a defense, shotblocker" type of big guy, I also think that if we can't get one, we need a big guy anyway. We may be placed at an awkward position. Drummond may go before we pick and Henson would be a big reach at #5. All is not lost as we still have Hassan who I have confidence can play ball some day. Let's not forget that we have a shot blocker already. It is interesting we haven't brought in Robinson but it's way early in the work out process so let's not start to hyperventilate. We have to bring in Robinson, though, as he is the only guy besides Drummond within reach.
I smell a trade but I do not think it is a trade down. There are a couple teams with two first round picks, right? I say we go after one of those. That is as much a reason to work out guys who might be mid lottery picks as trading down.
I wish we needed offense or just a big competent center. When I was scouting Henson, Zeller caught my eye. This guy is fundamentally solid and as much as I dislike the term BBIQ, he's got it. He is quick posting up and a rough tough offensive player. As the videos I have seen didn't show his defense - do they ever? - my dirty little secret is that I would be happy with Zeller. Yes, Tyler Zeller. No one has discussed him and it is as if he is totally off the KingsFans radar. He is a legitimate 7' and 250 pounds. He passed college teammate Henson in the mock drafts or at least when I last looked. Makes no difference. You get what you see. He is not a project. I am talking about the illogical attraction to a certain player that I am sure all of us have. Did I mention he is 7'?

Don't know his reach and don't care. This IS illogical, remember.
In closing, my fellow Americans and the stray non-American so sadly attracted to this team, we seem to be targeting a big man and that is OK by me. I also think there is a high chance that we are keeping #5 but trying to trade to get a lower pick in the lottery range.
