At this point in time I'd take Evan Turner over Wall as Turner would fit perfectly at the 2 spot next to Tyreke. I don't think Turner will last past the 2nd pick, and he could possibly go 1st.
As far as Cousins I'd take him at 3 in a heartbeat. I've watched him play numerous times and he's going to be a big 270 pound load in the paint who is a fantastic rebounder and plays with the mean-streak you want from a Center.
I wish I could make everyone who has doubts about Cousins watch the Kentucky/Tennessee game which took place a few weeks ago. Cousins was just a monster, and solidified my choice for top big man with that performance.
I do agree with one point though. After the big four (Wall, Turner, Cousins, Favors) there isn't another sure-fire potential all-star level talent which fits for the Kings.
So even if you end up with the 8th pick in the draft you still might be able to get the guy you want. To me, the next two guys I'd go for would be Wes Johnson and then Cole Aldrich.
Wes Johnson, I've seen play a lot, and I really like, but he doesn't have the ball-handling skills we'd need if we tried him at the 2, and I think a trade would have to be made if we picked him up as we don't need him, Donte, and Casspi. (I'd probably put him ahead of both Donte and Casspi, if he can show he's got good defensive chops. Donte gets the edge for me, until Wes can show good man defense)
As far as Aldrich goes, I have to say that I've watched him play a few times and have never walked away overly impressed. He does bring all the things we say we need, (Man Defense & Rebounding) along with decent shot-blocking and athleticism. So he won't be the 'sexiest' choice, but he could turn out to be the absolute best fit for meeting this team's needs.
After those six guys my next two would be Udoh and Whiteside, and both would definitely be available in the top 10. So I guess I want a pick with-in the top 6. And if that doesn't happen, then the guys I'd be most interested in will still be available regardless of where we pick.
One final note. If we pick Monroe I'll be physically ill. I don't care how skilled he is and how much improvement he showed in his rebounding this year. I want nothing to do with him.
And as much as he seems to be a typical Petrie pick, I really get the feeling that Petrie is working towards a tough, physical type of team, and will stay far away from Monroe as well.
