Of course you're not going to plug all these holes with trades, but there are some spots where we need some more help at than at others.
Bishop did a great job in relief of Barnett. There's a hole at ILB, but with the guys we have and Poppinga able to play inside a bit, as well, we don't need anyone there.
Peprah and Collins are the only guys we have left at safety right now, but I can imagine that we just sign someone untill Bigby and Martin are back.
The RB position could use some help. I don't see why everyone sees Starks as some kind of saviour, since he had a good, but not great college career... at Buffalo. And to add to that, he hasn't been healthy in ages.
NT would be a position where we could use some depth, but trading for one is next to impossible, since most teams are struggling to get even one decent player at that position.
And then the OLB position. We didn't get hit really hard with injuries right there, but as soon as Clay goes out, we're done. We can't get pressure to save our lifes. At least, not when bringing 4 from a normal package. I'd really like for us to take a look at a guy like Travis LaBoy again. I've liked Parys Haralson, as well, although he's a starter right now, so I don't know how willing a team like SF would be to give him up.
So really, the positions I'd like to see us get some help are #1 OLB and, maybe, #2 HB. Although I can imagine that we'd like to see what Jackson can do after last weeks showing.
