What is your definition of a successful season? lot of TD passes? lol My definition is a QB playing well enough for his team to make the playoffs and win atleast 1 game.
"Team". Key word is, "team".
You say Romo's only good season was 2014 but he put up similar numbers in 2013 and 2011.
34 TDs, 9 INTs in 2014.
31 TDS, 10 INTs in 2011 and 2013. More yardage in these season. 2007 wasn't bad and neither was 2009.
Your measurement of a good QB appears to be largely independent of the QBs play. If they make the playoffs and win a game, the QB is good. If not, the QB is bad. Romo had his flaws but to say he only had 1 good year is basically an admission of ignorance. List me the QBs who have had a 30 TD and 10 INT season - or better - over the past 5 years. Hell, go back to 2000.
Guess how many QBs have had a 30 TD, 10 INT season since 2000. Eleven.
Guess how many QBs have had more of those seasons than Romo. Two. Rodgers and Brady. Only 4 QBs have had more than 1 such season. Rodgers, Brady, Manning, and Romo.
There's no need to revise history with Romo. Everyone knows the story. Top notch QB with piss poor management, a weak supporting cast, and horrible coaching. Put Romo with a competent franchise and he has a Superbowl ring.
