Buffalo gets a steal as Neither Jacksonville (Monroe, Britton), Denver (Clady) or Miami (Long) need tackles, they get Williams no matter what, but if they trade down, they also pick up a future pick. Thats why it's such a smart decision.
Sounds like you're running all those draft rooms. Good work I'm surprised with all of that work you have time to post on here. I honestly don't think Berry will be on the board at 9, but if so and it only costs us 13 and next years 3rd I wouldn't be mad. I have a feeling if he's there that long, then we won't be the only team trying to get up there to get him.
I'm not on the Spiller bandwagon either, but a great player is a great player. If he falls to us at 13 and he's the highest rated player we should take him. I think we need to address our offensive line more than safety or RB, but the BPA model seems to work so much better than drafting for a position of need, unless the BPA & your position of need are so close in rating that it makes no difference.
