Yes, that is a telling stat. This defense cannot stop anybody in the usual way. A tuirnover is the only way they are getting the othe team off the field. That is very scary. I would rather have three and outs than TO's. It is more reliable to count on a three and out than a TO.
Also the OL needs to be able to push the other DL back on a goal line stand. This OL is embarassing.
