That's all fine, but once you get past the first 8-10 picks, there's a lot of difference of opinion about who goes exactly where. I'm sure there were several players who were all "slotted" about where Booker went, and McDonough had to choose one of those several.
On a slightly related note, Tatum has really tailed off recently. Leading up to the last draft, I preferred Tatum to Jackson, but since Tatum was off the board by the time the Suns picked, I was okay with Jackson. It's a small sample size, but over the last four or five games, you'd have to say that Jackson is looking like the more dynamic prospect. I really hope he can keep it up through what's left of this season.
