I think the coaches feel the same way. It is pretty rare to put an experienced backup QB on the field at multiple positions. With our spread offense, and Babb's ability to run, we risk needing MD as a QB. There is as much argument to keep him off the field as put him on the field.
With our situation (talent, but always in need of improvement) we cannot afford to leave MD on the sideline. We need him on the field. However, there are a lot of multi-purpose athletes out there that were superstars in highschool, but are not going to start ahead of position talent.
If MD took a hit that even slightly winged him, we would be forced to limit our options with Babb. As I totally agree with wanting to see MD on the field, because he will contribute, I am reluctant to say that the coaches are ignorant. I think they are proceeding with enthusiastic caution.
