I agree, I think DT depth is a potential issue. Or more accurately, getting some youth in there.
As for LT, we're probably okay. There's enough guys in camp that someone should emerge as a decent backup. Probably Tony Pape. If McIntosh comes back healthy, we're in great shape.
#3 WR - I'd like to add a speedster; I'm not sold on Snoop Minnis being the answer, and I'm sure not sold on Derrius Thompson. Maybe Sam Simmons or JR Tolver can do something.
KR/PR - Sam Simmons, Terrence Wilkins, Fred Russell...someone decent is bound to emerge from this group.
FS - we're fine. Freeman or Edwards should do the job well.
MLB - I'd feel better about an experienced backup here too. I'm guessing they're counting on Moore, Bua or Jenkins to be a 4th LB, filling in at all three spots.
So, the way I see it, these are our remaining needs:
LB depth, esp. MLB - (I'd really like them to get someone that could allow us to play a little 3-4 and give the offense a different look now and then, though our D obviously is poorly suited for that on a regular basis)
