Romo had a decade to prove himself and came up with a couple playoff wins. Some of those most critical losses fell directly on Romo making ill timed throws, forcing the ball instead of getting rid of it and his injuries were largely a result of him hanging onto the ball too long. In other words, his most epic failures were in large part due to himself not the coaches, defense, o line, turf surfaces, weather patterns and every other excuse Romo lovers (who used to bash him) now make for him.
The two years we made it to week 17 and just had to win, Romo went out once the week before and another time a few weeks before, leaving JG with two incompetent QB’s to win what was essentially a playoff game with little to no time to prepare. Part of Romo’s weakness that ultimately cost him his career (and the Cowboys a potential playoff spot) was trying to make too much happen and not being smart with the football.
