ARVADA — It was a sun-splashed Monday evening on the Pomona High School practice fields, four days before the season opener. Hip-hop music blared from a bass-heavy stereo, covering the team with the kind of chest-puffing confident tunes appropriate for a team with the highest of expectations. State title expectations. But, says Pomona coach Jay Madden, that’s not foremost on his team’s mind. Sitting on the field, keeping a close eye on the practice unfolding before him, is a player on whom many of those expectations were built.
