It's not unreasonable to think he'll play the "vast majority" of games this year but when he misses a game we usually lose. The odds of Romo missing at least one game this season is pretty high based on his pattern the past 3 years. The one game he missed in 2013 had our entire season on the line and we lost with what many felt was the best backup QB in the league in Kyle Orton. Although Romo played in every game in 2011 and 2012 we still went 8-8 and missed the playoffs due to coaching mistakes and having a mediocre at best defense that can't make critical stops. Romo missing games the past 3 seasons points to his body breaking down due to his advancing age.
When any team loses their starting QB their offense is going to lose some punch so your defense has to step and ours never does. It didn't step up vs Atlanta last season when we had three 14 point leads and it didn't step up vs NO. Our offense never saw the field in OT vs the Saints. The SB teams the Cowboys had in the 90s could win games without Aikman. They won with Jason Garrett and with Steve Beuerlein during the regular season and even in the playoffs vs Chicago.
Those teams had the coaching and the defense that allowed those teams to not miss a beat in Aikman's absence. I've given all the reasons why I don't think we'll ever win a SB with this current corp group. Romo and Witten are aging and we simply don't have the head coach or the defense to go deep in the playoffs. There's simply too many holes defensively that good offenses/QBs can take advantage of.
You could be right on all of that... and you're certainly correct that we've been losing the games that Romo has missed.
It is just a pet peeve of mine when it is assumed that Romo is going to be injured all season (not saying you said that). So many fans (particularly Washington, Philly and NY fans) act like it is a foregone conclusion that Tony is going to be hurt most of this season. His back is better than it has been in a long time and last year was a collar bone... not exactly something that is a recurring injury (unless you rush back like Tony did last season). That is without mentioning that he had a Mumford procedure so the collar bone won't be an issue going forward.
If they want to argue that Tony is in his mid 30's and so is a little more brittle than he was 10 years ago... then I can at least understand that argument, although they'd have to say the same thing for Brady, Brees, Eli, Rivers, etc.
Football fans are notorious for looking at recent events and thinking that's how things are going to be going forward. Just because Tony missed last year and is in his mid 30's, they think he's going to stay injured. Nevermind that it was a collar bone and he had the procedure to make sure it doesn't happen.
Like I said... just a pet peeve of mine really.
