I guess the Cowboys just decided replacing Parnell was filling a bigger area of weakness.
Right. I don't agree with them, but that doesn't mean I'm correct.
I admit that I had concerns whether Weems could handle the backup role, but I didn't feel that was as vital as doing whatever we could to shore up the running back position. That doesn't mean the running backs we have won't succeed, only that there are plenty of reasons why this team should have doubts about it.
Bringing in Buck Allen wouldn't have removed those doubts, just simply have given us another option to throw into the mix, hoping someone will emerge. I probably would have taken Allen in the third rather than Green and possibly taken David Cobb or Jay Ajayi in the fourth instead of Wilson (or traded down with both Cobb and Ajayi available and tried to grab one of the two).
That might seem excessive, but at a skill position where you don't have a clear-cut starter, I don't think there's any such thing as overkill.
