The only move that is questionable on that list is Kellen Clemens...if he had what it takes, this team wouldn't constantly be looking for a quarterback.
Jets actually traded down in 2nd round (with Skins of course), and then just back up a couple selections (to get ahead of Vikings) to draft Clemens. So he was more of a trade down than trade up. With the Skins 2007 pick we netted from that trade down, we essentially got Thomas Jones. So we could have selected fatty Lendale White in 2006, but instead we traded down and got Clemens, and had some ammo to acquire Thomas Jones the following year. I like trading down.
