Aside from OL, what position group do the Bengals need most improvement?

[TKUHL]

I voted LB as the position that needs the MOST improvement. but its the D-line that I think needs the 1st pick( depends on who is there). I think the line will be better with Billings and a beast of a DE in the draft and a DT in a later round. Its never the sexy pick but the D line can make the whole D better or at least seem better than they really are, just like the Oline is making the Offense look worse than they really are. The LB group we have is just a mess and needs the majority of attention. I would try to get 2 LB's out of the first 4 rounds but of course we need a C. So it will look something like this. 1st DE 2nd-C/LB 3rd LB/RB 4th DT/S/TE
