Apparently, you missed a few things. One is that the 3-4 works a heck of a lot better with legitimate pass rushers at both outside linebacker spots. That was a big part of the team's improvement this season. The other is that none of the other outside linebacker options on the roster can play. Chickillo sucks and he is the best of what they have. Losing Dupree opens up yet another hole on a team that has very limited resources for next season.
