I will give examples.
In 2006 - he bobbled the snap. I get he was a holder but was a huge end of game mistake.
Sure, it was a mistake, but given that he was the only starting QB to be a holder for as long as I can remember, and that the rule got changed the offseason after to take control of the kicking balls away from the home team, I don't think that this should be a huge deal, but if you want to blame him for this one, go ahead.
In 2007- he had what you call his Hail Mary interception. I don’t fault him for the interception, in and of itself, I have a problem with the fact he rushed that throw and gave his receiver absolutely no shot at catching the ball. He had time to scramble, give receivers more time and given someone a shot at a reception. It wasn’t “Hail Mary” as we were only 20-30 yards away and a 1st down still could have been achieved too.
I haven't had the heart to rewatch this play after seeing Crayton inexplicably quit on his route the play before which caused the loss. I do remember that Romo had been knocked down in over half of his 2nd down passes, I think it was around 2/3 of them. I might remember wrongly, but I don't really think there was time for a first down either.
In 2009 he was a turnover machine against Minny. While he only had 1 interception, he fumbled 3 times losing 2.
Cmon, you can't reasonably blame Romo at all for this one. As bad as Dak's Atlanta game was, imagine if there were 2 players that consistently got more pressure than Clayborn did, and another one on the line was getting close to that amount of pressure. You could put any QB in history into that game, and they would all look like scrubs.
In 2011 - he had a good stat line agianst NY in week 17. Problem is our offense sucked when the game was tight and racked up stats when down big.
Hard to blame him for this one considering the offensive support he had, vs the blazing hot NYG defense which took them all the way to a Super Bowl victory.
2012- threw 3 interceptions against Washington in week 17, including the last one with under 2 minutes down by only 3. That pretty much ended the season.
This was his worst game of the bunch by far for me, and was the only one I put any significant blame on him for. It didn't help that he again had terrible offensive support overall, but this was a huge stinker that he deserves plenty of blame on.
2014- he actually came through against the Lions and would have come through late agianst the Packers if Dez would have wrapped the ball up.
