I think Joe Buck and Troy Aikman do a pretty good job as Fox's #1 team (although Troy never really says anything interesting.)
That being said, I watched a replay of the last moment of the Super Bowl from yesterday and saw/heard something fairly interesting. From the moment that Plaxico Burress caught the game winning touchdown (with Buck saying, "Manning lobs it. Burress alone. Touchdown New York!") up until the extra point was kicked, neither Buck or Aikman said a word. It was just pictures and crowd noise.
That, my friends, is good announcing.
