I don't have high hopes for Miami and playoffs. They fold down the stretch, are terrible in bad weather, and usually only have any chance at the playoffs when they start hot.
The offense and timing are vital, which is why it will never beat good teams. They won't win in poor weather or on the road. Any kind of semblance of a pass rush can also usually beat them.
Tua is a nice guy and I wish well for him.That being said, he chose to get leaner this year despite the recommendation to have some weight on him for protection.
