I'm starting to get confused on who/what I want

Thing is...you can't fix just one. In order for Samuel to be effective and make plays, our pass rush would have to improve. If we can do both, then we would be able to allow a ball-hawk like Samuel to maximize his ability. If we only do one, the other will suffer. Samuel will be a more expensive Jason David if we don't upgrade our pass rush. But if we upgrade our front and not the secondary, we will still get burned there too because our secondary just flat out can't cover.

Basically, I want an upgrade at about 5 positions on D(CB, FS, WLB, MLB, DT) so that, if we bring in a playmaker like Asante Samuel, he can make plays.
