I don't know much about the charting, either. I think, however, that given the chances of hitting on 3 or 4 players that we'd have to give up to get one, I'd take my chances with the 3 or 4.
As we learned with Mike Williams, there's no sure thing picking that high. It's a crapshoot, but you never know when you're going to get an andre reed or thurman thomas.
