Dude, Need is part of the best pick available equation. What he is saying is after you set your board and say "ok, we NEED a WR2, Saftey, Offensive tackle, so these round 1 players are graded higher slightly than these RB's, QB's." WE WILL NOT DRAFT a Round 2 Left Tackle in the first round just because there has been a run on all of our need positions, we will draft the number one defensive end, outside linebacker, cornerback.. etc in that ORDER. If we are in round 2 and a round 1 talent is available at running back, were taking him.
You might wonder how we know this? LOOK AT HIS DRAFTS, he has drafted for need unless there is a higher round talent available, Kony Ealy probably had a round 1 grade, Moses the left tackle that EVERYONE wanted last year couldn't even start at right tackle for the redskins this year and then was put on injured reserve with a foot injury. I would say we hit on Round 2 in the draft by drafting CORRECTLY.
