Yeah, only Harrison Barnes and maybe Perry Jones would move into the top 5. I doubt Jared Sullinger would get any interest, maybe from the Cavs at 4 just for the hometown hero effect.
Sullinger would still be top 5. My guess is the 1-2 would still probably be about the same, as Williams was never worse than 3 on any mock draft before they all pulled out and Irving has pretty much always been the consensus 1. My guess would be (roughly):
1. Irving
2-3. Williams
2-3. Barnes
4-5. Sullinger
4-5. Jones
6. Kanter
7. Knight
8. Henson
9. T. Jones
10. Morris/Walker
