Though the Bears have not used any of their pre-draft visit to work out any defensive tackles, Michael C. Wright at ESPN thinks that's where they're looking:
Outside of starters Henry Melton and Matt Toeaina, rising second-year man Stephen Paea is the only defensive tackle on the roster with experience, meaning this is likely a position the Bears would look to address in the NFL draft.
A number of other mock drafts have suggested the Bears will use their first round pick (19th overall) to select a defensive end. Whatever the case, bolstering their pass rush is a clear need for the 2012-2013 Bears. Strong prospects like Fletcher Cox, Dontari Poe or Michael Brockers could all add something to the Cubs defense.
