Totally dependent on Romo's health. If he plays about 12-14 games I think we win at least 9 or 10, if he misses 6+ games we probably finish somewhere around 7 wins, if last season repeats itself, we know what that looks like.
With all that said, I'll go with 9 just because it seems like a happy medium. I think Romo is destined to miss a few games because he basically misses at least a game or two every year but I don't want to throw out a prediction based on him missing half the season either.
Clearly this team has the potential for 11-12 wins if health permits like it did in 2014, but all it would take are a few key injuries to knock that number down real quick.
