I took Mel Kipers Top 10 OL list for this upcoming draft
I pulled the ON3 composite rankings
15 out of the 30 were Top 260 players overall
12 out of the 30 were Top 150 players overall
9 out of the 30 were Top 100 players overall
I considered 9 out of the 30 as outliers ( outside the top 30 of their position)

And do it by percentage. Remeber, only 32 players end up 5 stars and a total of 425 or so 4 stars. Every player after that is 3 stars or lower and there are thousands. So the percentage of 5 and 4 stars drafted over 3 stars and lower is much higher.
