2015 is set up for Romo to prove he's worthy of being an NFL MVP. NFL players don't respect Romo given DeMarco Murray's 4th best player in the league ranking. That as much as anything says who they feel was responsible for Dallas' success.
I disagree with that, but do agree Dallas running backs have dropped to below-average. The offense is thus completely on Romo's shoulders with an unbelievable offensive line, future Hall of Famers in Dez Bryant and Jason Witten, and an ever-improving Terrance Williams.
The defense come October will have added Greg Hardy, Sean Lee, and Byron Jones for a major boost in talent at each level not even counting Demarcus Lawrence and Randy Gregory.
If Dallas can manage to head into the bye week 3-2 vs the Giants, Eagles, Falcons, Saints, and Pats, they will have a major leg up for the playoffs (Eagles being a key game).
I could also see a 2-3 start with a shaky defense and lack of an offensive identity out of the gate with the press raining down on Romo, Garrett, and the Jones family while heaping praise on Demarco Murray and Chip Kelley.
But in the end it comes down to Garrett's commitment to a 50-50-ish run-pass ratio giving Tony Romo the opportunity to execute. I have a feeling the defense will (finally) have his back.
