I would think if we go FA anywhere it would be at LB due to our cap situation and that's the cheapest position to FA (past Special Teams).
I tend to agree with RF in that we have Kiwi, Tuck, JPP, Ojomo and Tracy available as DEs in 2013 and that would suffice enough for us to address more pressing needs in this year's draft (I'd be more worried about DT for instance).
But it will also depend on where the chips fall in the first round.
They need to improve the pass rush in some way I dont care where it comes from. they need to get more pressure on the QB. If they take a DT early this year we know they have absolutely no confidence in Marvin Austin
