I am out in Portland, OR and on the local sports talk this afternoon they had a segment dedicated to ESPN Sports Science director (forgot his name). He detailed a study that they do each year on the top 32 draft prospects from each position. They put them through a battery of tests, metric type tests, to evaluate them based on a formula way different then combine type stuff. Real nerdy stuff.
They end up grading out the prospects based on these tests. For QB's I remember a few of the categories (release point, velocity, decision making, and a bunch of physical/explosiveness tests). It was really interesting what they came up with for results. The most striking was that they have not missed (in 4 years) in predicting top talent positionally. For example they correctly identified the last 3 Defensive rookie prospects (Suh, Von Miller, and Keuchly).
He flat out, without reservation, said that EJ was far and away the best QB in this class, and it wasn't even close. He applauded the Bills pick and where they took him. They had EJ score a 90 which put him between Andy Dalton and Big Ben, who have also taken the SS tests.
I read somewhere on the board that the draft is about managing where you take players in different rounds. I completely disagree - I think it is about getting the best player at a position of need (when you are a team like the Bills). I think we absolutely did that with the EJ pick...here's to hoping that SS is right for another year!
