There is no chance in hell we a running Tampa-2. That formation is weak against the run, so you need outstanding run stuffing DTs. The Colts can play Tampa-2 without run stuffers because they score a sh*tload of points and opposing teams MUST throw to keep up. We're not running Tampa-2 without Peyton Manning, or big changes at the DT postion.
The Tampa 2 doesn't have to be weak against the run. Tampa has been close to us in run defense for the past 4 or 5 years. Plus their passing defense has been better. Teams run against them because they struggle to pass against them not because it is easy. It is true that the middle linebacker plays deeper in coverage but it just means he has to be mobile and quick which Beason surely is.
If we keep some big guys on the Dline we can be good against the run and the pass. Might be an opportunity for a little guy Like Hillee Taylor to get some PT. He should be around 255 by the time the season starts next year.
