Byrd and Harris for me are the only dark picks. Byrd as a saftey intrigues me, but if they don't use him it's pointless. I hope they do. Harris as a LB prospect is also intriguing, except that they list him as a pure CB. If he can transition and not play solely ST, then it's all good. I still give an A- on the top end if they can transition into their projected positions and play this year.
A+ would be reserved for an exceptional trade / pick, something like getting Nelson in the 6th (would not have happened, I'm happy where they got the steal and it was an exceptional value at that pick). If they could have taken him lower, A+ draft easily, not that I rated him that low. I just believe some D or O line backups would have put us over the top. Given that we can get a good LB in FA.
Personally, all but the harris pick is AWESOME to me.
