Yeah, that's the one I was struggling with. I don't have an issue with Dallas at #15. But the Dolphins did add back #99 to their defense, which automatically makes it better. Their offense should be better too with Pennington in his 2nd year of that system and an up and coming Ted Ginn. It will all depend on their offense. FYI, had the Eagles retained Dawkins at safety, I would have them at #1.
Cowboys have some real issues... 1st - Depending on Romo 2nd- Depending on Romo 3rd- Secondary 4th-Jerry Jones 5th-Receivers
Their defense is mediocre as a whole, which will be as much of a problem as anything else you listed there. Romo's career will start it's fairly immediate decline this season. He won't be starting for any NFL team in 2011.
8-8 is pretty much about right. They won't be any better than that, and the season could easily spiral out of control into what would end up being a rebuilding year come 2010.
