Initially, the vacated fourth seat was to feature a rotating series of guest analysts, with Jimmy Johnson returning in Week 1. John Elway sat in during Week 2. For Week 3, Johnson returned, and took over the position permanently (he remains on the program to this day). Jimmy Kimmel left the program after the 2002 season a month before the premiere of his late-night talk show on ABC, "Jimmy Kimmel Live!". He was replaced by comedian Frank Caliendo – at the time, a cast member on Fox's late night sketch comedy series "MADtv" – who had previously guest starred during Kimmel's skits (performing his well-known impersonation of John Madden). Caliendo's prognostication skits began to feature his various spot-on celebrity impersonations, including Madden, Jay Leno, Jim Rome and George W. Bush, as well as show hosts Brown, Bradshaw, Long and Johnson. James Brown left the program after the 2005 season, in order to return to CBS to host its rival pregame show "The NFL Today".
