The album's lyrics are a slight departure from Some Kind of Zombie, as they focus more on missions and the word of God being spread, as shown in "Hands and Feet" and "Jesus Movement"; a theme that would reappear in Worldwide.
According to guitarist/songwriter Bob Herdman, the idea for the album was to "have more fun — not take this music so seriously — and just make songs that people like".
Most of the mastering was done by Ted Jensen at Sterling Sound Studio, while digital edition was done by Paul Angelli.
However, he writes that "the funk riffs still sometimes feel grafted onto the songs, which are melodic AOR at heart, and there are a few musically awkward moments here and there".
He also wrote that Underdog surpasses "each album in talent, song craftmanship, tightness, bold message, and overall greatness.
Also, "Mighty Good Leader" was sampled by rapper Aceyalone for his song "Superstar", which was featured heavily in the 2004 video game ESPN NFL 2K5.
