The draft value chart lessens as you move into later rounds guys, round 3 trade ups cost less than round 2 trade ups. Always have, always will.
Tanny also got us Kyle Wilson, Vlad Duccasse, and Vernon "The Bust" Gholston each of which contributed to the disastrous depth the Jets endured the past few years.
The last 6 years were 4 picks in 2007 + 6 picks in 2008 + 3 picks in 2009 + 4 picks in 2010 + well you get the point. That's what Tanny did to us.
