im going to ignore the second question but it depends. top end picks are high enough that they are worth more than 1/4th of a partial grade, and the highest guys, like the #1 overall pick, are probably worth at least 1/3rd partial grade. however, by the time you get into the 2nd round, its really a fairly small factor. probably down around 0.1 partial grades, maybe a little higher, but probably less than 0.2.
