I've been doing like a million of the draft simulator things. While I love the idea of trading down for more picks, it would be tough to have the #1 pick and not end up with a guy who is a day 1 starter and likely pro-bowler.
Overall, I looked at the roster again and can't believe how bad the defensive line/edge is. If they used 4 picks on the defensive line, I wouldn't bat an eye--there's a chance all 4 of those guys would get the most playing time on the D-line this year, it's that bad currently.
