Here are notes I took while looking at what happened from 2006 - 2015 (games Romo played). Not going to clean them up but feel free to take a look. Based upon
@erod claiming the defense would virtually always give up the lead when the offense would score to tie or take the lead with 3-4 minutes remaining, I went back to see how many times the defense failed after we scored in the 4th to tie or take the lead. I extended the time to get a better picture of what occurred. Not trying to be biased. Just wanted to see what really happened. Sometimes the defense just flat out failed by themselves. Sometimes the defense failed but also had hep from the offense and/or special teams. Sometimes they just came through.
