I think the draft seeding is important. Not so much as related to chances at the #1 pick but rather, how far you can drop. With the #1, the worst place is 4th. Historically, the first 1, 2, 3,... picks can be really good but then things drop off fast. Odds are against us getting the actual #1 pick in any case but I think it is important to protect the floor of the pick.
That value is true in terms of both the actual players and in trade value. I guess the difference between 4 and 5 as a worst case is not a huge deal but it is something. It is different every year but there always seems to be a drop off at some point.
