Romo has thrown twenty six 4th quarter interceptions in his entire career. That means, he is throwing a little over three 4th quarter interceptions a season. Three.
K, now how many times has he fumbled late in games? How many overthrown passes? How many dropped INT's, that lead to a 3 and out? The botched field goal snap he dropped. Balls snapped past his shoulder? Sacks he takes instead of getting the ball out?
It's not JUST INT's that have cost him, and his team late. It's mistakes. Overall, general, mistakes. 8 years he's been back there, and still havin issues like those every year.
Sometimes he wins the game, sometimes he costs them the game. He's exactly that, an average guy whose had a lot of weapons during his 8 years.
