I've never been clear on what constitutes a 1st round grade. Why do teams only hand out 15 or so per year, when there's 32 1st round players? Sure, there will be a lot of overlap between the talent picked at the bottom of the 1st and at the top of the 2nd. But when your "borderline" zone extends halfway up the round, that's way too long of a border.
A number rating like what NFL.com uses makes it easier to compare prospects from year to year, but it makes no sense to go on a forum and talk about a 6.5 rating vs a 6.3 or whatever, because it's not like any of us have memorized one website's rubric.
Anyway. I'm still not that high on this draft class. I like Armand Membou, but where would he go in last year's draft class? To flip it around, where would Tyler Guyton go in this class? I wouldn't be surprised if he would be getting top 10 draft talk right now.
