I have tried to stay out of this one. I agree that Romo needs to take on more of a leadership role. However, I find it interesting that we equate leadership to body language or how they handle a press conferences or interviews.
I have seen many suggest that Manning is a field general and demonstrates leadership qualities etc., yet not 4 years ago he had his detractors too. You can look on the web or through these very forum archives. Talk was that Manning put up pretty stats, but could never and would never win the big one. I've seen articles and posts talking about his body language too, that he pouted on the sidelines, moped off the field with his head down, etc. As a matter of fact, not too long ago these same types of posts followed the younger Manning as well.
Romo is right in this aspect, that winning suddenly makes someone appear to be a leader from the outside. However, he should have never made those comments.
