I feel bad for our safeties. They get blamed for all the deep balls, and for being out of position, and that they aren't sticking to their assignments. In reality, the problem with our defense is 3 fold:
1: no pass rush. The Tampa 2 relies on being able to get to the QB with an outside passrush and to get their quickly. Guys like Dwight Freeney for Indy are exactly what you need for the Tampa 2, and is exactly why Indy's first pick in the 2002 draft was Freeney. We do not have a DE on our team right now that is even remotely capable of this and this is simply a matter of recruiting.
2: Terrible MLB pass coverage. I love Jessie Smith's effort and he is rock solid at stopping the run, but he has TERRIBLE pass coverage and in the Tampa 2 you absolutely, without question, require a MLB capable of reading a play and getting into coverage. This is why I feel bad for our Safeties. They are indeed out of position on many plays, but it's because our MLB is just way, way too slow and out of position to get back to cover the deep middle. His responsibility on a pass play is deep over the middle and I can't remember now how many times he's been about 20 yards to shallow. This forces the Safeties to cheat to the middle but they screwed having to cover both deep middle and the entire sideline. I agree that the safeties look bad, but the problem is with the MLB. If we could get a FAST MLB (possibly moving Raven over next year) that is better than Jessie at reading and reacting then we our safety play will immediately be better.
3: DT must be more athletic. In the Tampa 2, the interior Defensive Lineman are responsible for the run; because the MLB has to drop into coverage, your tackles must be able to consume the middle of the line giving the MLB an easier read on the play, we simply do not have the horses in the middle to be able to pull this off yet.
In total, we simply don't have the personnel on the field to run our defense. It would be surprising to me to see any assistants or Bolt released when they need time to groom players into the system they are running. The same goes for the offense, we are just beginning to put the pieces in place now. The offense is further along than the D right now and it shows with some glimmers of what we might be seeing in a year or two.
