I was not crazy about the hire, but I think overall he has done a good job. I have stated so several times, especially last season. IMO he (nor anyone else) can really change what we can do on defense from a scheme perspective. We will only be successful if we send numbers and take a lot of chances. His hands have been tied this year because our offense cannot win a shoot out that they could have last year. He cannot take the chances he took last year because games would probably get out of hand. In order to have a better defense we are going to have to get better on offense. That is just reality IMO unless we suddenly get a mature front 4 that can apply pressure without bringing extra numbers. We have not had that in a while, and we are not going to have that next year. Over time our freshmen and sophomores may be able to apply a consistent pass rush with only 4, but that is more than a year away and they will have to develop/mature.
One side note here. We can get a lot better at the fundamentals, especially tackling. That would help a lot regardless of how aggressive we are. This is the only area where I feel like Ted can have a sizable impact, and should have a sizable impact on what we are able to do on the field.
I personally see no reason to change DCs unless Ted just wants out. Feel free to disagree, but go watch other games with your favorite DC and imagine what they could do with our roster. A lot of defenses are successful because of the front 3 or 4 guys, and that is true from high school to the pro levels.
