I took a look at the ten drafts from 1990 through 1999, and classified players as either world-beaters, solid pros, disappointing pros, or busts. (I stopped at 1999 because that gives us at least five years of experience to evaluate each player.)
I came up with this matrix. The total points reflects 2 points for a world beater, 1 point for a solid pro, 0 points for a disappointing pro, and -1 points for a bust.
Code:
Position in Draft World Beaters Solid Pros Disappointing Pros Busts Points
1 3 3 1 3 6
2 3 1 1 5 2
3 3 2 2 3 5
4 4 2 4 0 10
5 2 2 2 4 2
6 2 5 0 3 6
7 2 4 2 2 6
8 1 5 3 1 6
9 2 4 4 0 8
10 3 5 2 0 11
11 1 4 3 2 4
12 2 5 1 2 7
13 1 6 0 3 5
14 1 4 2 3 3
15 0 7 1 2 5
16 2 4 1 3 5
A quick trend line shows no average difference in drafting round, since you lose only .0014 points for each draft pick you drop. If we increase the value of a world beater to 2 points, the difference becomes more significant - 0.15 points lost per draft number you drop.
Offhand, this tells me that the draft order in the top half of the first round doesn't really impact one's ability to find a solid pro, but it has some impact on the ability to find a world beater.
