There was a poster who used to post on another forum, who made some formulas that tried to predicted the success of 3-4 OLB's and 3-4 DE's (and other positions, which i didn't do the calculations for, since the results weren't as good) based on their combine numbers (mainly the Vert/Broad, and Short shuttle/3 cone) and broke them down into different groups. Here's the tread of him describing how it works and the formulas.
So i've been doing this since he's been gone, and making a spreadsheet of the results from the numbers last year, and i figured since its easy that i already have the template down, just to throw it up this year. So below is the google Spreadsheet i made for this year. There obviously wont be anything there till tomorrow (other than weigh in/Bench numbers which i already have up), and just to note, i pretty much put anybody thats a DE or OLB, so guys like Gholston are there despite him not having any chance to play OLB, so dont put any stock into that...
