It's probable we already have Trufant's replacement in either Thurmond or Lane. maybe even Maxwell.
I disagree about the WR's. Sure, we need a better possession guy, but if Baldwin was having a year similar to last year, we would not be complaining. Look at Rice's numbers; they're pretty good for how little we throw the ball. Also, Tate doesn't have the amount of catches, but he's a big play every time he gets it, there's points going to be involved. He also gets in the end zone a lot for how little he touches the ball. Going back to our 3rd guy....Edwards and Baldwin aren't getting it done, but if we had a very good 3rd WR, our Wr corps would be much different.
I still like Miller and I think he's what we need at TE for this offense; Cable requires guys that can block really well. Gronk would be perfect for us, Hernandez wouldn't (which is why Winslow Jr. hit the road).
Our biggest needs are: OL (our guys are good because of the scheme, but they aren't very dominant), OLB, Nickle CB (once again, that guy is probably already on the roster), 3 Tech DT (Jones is ok, but I'd like a guy like Suh or McCoy, who can pass rush and run stuff), and maybe an upgrade at our 2nd or 3rd TE spots....I'm not completely sold on McCoy but he can still progress.
