I don't think Dallas can win more than 10 games this year. 13-3 sounds really unlikely. What reason is there to think that they will be so good this year?
They are in a tough division and I don't think they've done a whole lot to get better. Maybe getting rid of TO will help but that's about it.
They really needed to clean house after the meltdown last season but they stood pat. I can even see them going 8-8 and missing the playoffs.
