I think we do need to draft an ILB. We need pressure up the middle to balance the guys on the outside. Sharper has some rush skills but Foreman has none. Foreman is just a reactionary guy that makes a ton of tackles 5-10 yards past the line of scrimmage.
If you look at the Steelers over the last few years, they have been more productive when ILB Kendrall Bell has excelled.
That said, I think DL is our biggest need going into this offseason. Payne and Walker just don't look as good as they did in 2002.
