I think it was smart to start conservative and get aggressive later in the game the other day.
Right now this is a team with a new quarterback, that needs to establish its faith in the quarterback, and the quarterback's leadership of the team.
If Cutler would've come out aggressive early and bombed with INTs let's say, it would've been quite the negative start to his tenure in Miami in terms of the above.
Instead, he managed the game in the first half, and then won it in the second. That's quite a good start.
