In that interview today, Kiffin was asked about this and at the end he said don't worry, there will be plenty of Bucs and Bears in there, too.
Plus he went through each position on defense and said he thinks we have 34 OLBs who can put their hand on the ground, and said he thinks we have the two tackles. Of course he'll tailor it once he sees how good the players are and what they can do, but it sounds to me like a fairly conventional 43.
Plus you have to remember he was telling Carr to look at Seattle. Probably because they didn't played more bump and single high safety than the old Bucs did. And Kiffin mentioned those two things today.
