A New Defense or an Old Defense?

With the arrival of Lovie Smith and the slew of signing on the defensive end, I find my wondering what our defense will look like this coming season.  Are we looking at a Tampa 2 whose style generally resembles the days of Dungy past or is he more of a blitzer?  Will the linebacker play deep into the secondary or does he stay up more?  Will LeVante David at the Weak Linebacker position still be more active than the strongside linebacker.If it makes a difference, what to expect from our new...or old...defense and how it may compare to Dungy's days is something I would be very interested in reading.
