I've spent the entire slideshow talking about the Dolphins' offense, which has been a question mark so far.
The defense has had it's questions as well, but it looks like things are getting better with that unit.
The Dallas Cowboys have one of the more explosive offenses in the NFL, yet their first-team offense was held without a touchdown when they faced off against the Dolphins' defense.
They faced pressure from both the defensive line and linebackers and couldn't run the ball. Their only hope was having Tony Romo throw it to Dez Bryant and Jason Witten, picking on Cortland Finnegan (covering Bryant despite playing as the nickleback when he was in the game), and that wasn't enough to score on the Dolphins' defense.
The most promising aspects of the defense was the ability to get to the quarterback. Cameron Wake and Olivier Vernon got to Romo three times, this following a five-sack performance against the Buccaneers (mostly by the second team). It shows this Dolphins' defense will be an aggressive one.
The interior should be fantastic as well, as Earl Mitchell has looked like a natural 4-3 defensive tackle, while Randy Starks and Jared Odrick remain at the high level they have played the last two years.
Of course, the linebackers were a point of concern throughout the preseason, yet against the Cowboys they looked their best despite missing Koa Misi. I still don't trust them too much, but they can at least hold their own, which is about all you can ask for from them at this point.
Miami's secondary has the potential to be great, even though it seems a bit boom or bust at this point. Brent Grimes will continue to be Brent Grimes, and while Cortland Finnegan is decent as Miami's second corner, it wouldn't be too crazy to see Will Davis or Jamar Taylor taking over for Finnegan sometime this season.
The safety position has plenty of concerns, including Louis Delmas' health, how they will adjust to (losing then regaining) Reshad Jones, and how well Jimmy Wilson will play in his place. Like the linebackers, the best we can hope for is that they hold their own.
Miami is good at cornerback, but great at defensive line. The safety and linebacker positions might have question marks, but they aren't as glaring as we once thought.
