Jim Nantz and Tony Romo were inseparable when CBS broadcast the Super Bowl two years ago. Next week, they won't see each other until they are in the broadcast booth a couple hours before kickoff. “For me, this is going to be very much like what we did during the regular season, but it’s completely different from what I have experienced in past Super Bowls,” said Nantz, who will be calling his seventh Super Bowl. Two years ago in Atlanta, Nantz and Romo arrived on Monday of Super Bowl week and had a busy schedule of watching practices, meeting with players and coaches, doing interviews, production meetings and various dinners.
