Aren't you helping the run defense by drafting a DE? After all a lot of the big runs against our defense come when our DE's fail to contain the cutback lanes or our OLB's aren't quick enough to get to the edge. A DE will improve our run defense a whole lot more than a DT can at this point.
We'd be a whole lot better off by signing a Barry Cofield type DT in FA and drafting a DE. We have a serious age issue at DE, Smith will be 30, Brown will be 32, and Wilkerson will be 30. Considering that's one of the most important positions if not the most important position in a 4-3 defense that's not a good problem to have. We need youth in a bad way.
