I'm o.k. with either Smith or Sparano. If I had a vote it would've been Smith purely because of Parcells involvement in Miami. He was the puppet master and had major influence behind the scenes in setting the table.
Belichick - really good job but let's face it, he had a ton more talent to work with compared to Smith/Sparano. And I dislike his arrogant ass.
I also think Harbaugh in Baltimore has done a great job. Especially with a rookie QB.
