As we've discussed, the Chicago Bears retained most of former coach Lovie Smith's assistants to give their new coach the option of keeping them as part of his new regime. The Bears did allow special teams coordinator Dave Toub to depart for the Kansas City Chiefs, and it appears new coach Marc Trestman at least will bring in new offensive coaches as well.
ESPN's Adam Schefter has already reported Trestman's first hire: Former New Orleans Saints assistant Aaron Kromer as offensive coordinator/offensive line. Kromer and Trestman worked together on the Oakland Raiders' staff in 2001 and 2002, and their respective backgrounds suggest that Trestman will call the plays in 2013. It also means that Mike Tice, the Bears' offensive coordinator in 2012 and offensive line coach in 2010 and 2011, will be looking for a new position.
On the other hand, you wonder if Trestman would consider keeping defensive coordinator Rod Marinelli and the rest of the Bears' respected defensive staff. That decision will be based in part on whether Trestman wants to continue the "Tampa 2" framework that Smith brought to the Bears in 2004 and has been well coordinated by Marinelli since 2010.
Hopefully Trestman will shed some light on that possibility during a news conference scheduled for 11 a.m. ET on Thursday.
