Joe "JB" Hall Jr. is closer in age to Montana's players than he is to the rest of the coaching staff.
The 25-year-old cornerbacks coach exudes high energy on the field, sometimes chasing players during agility practice drills and matching them step for step. It's his most noticeable characteristic, he said, and one that helps him do his job effectively.
"Obviously being a young coach, not too far removed from playing, I like to generate energy from the coaching staff," Hall said. "I think the players, they respect me for that. They like to have a little fun. And defensively, especially in the secondary, you've got to be able to fly around and have a little fun."
Hall caught head coach Bob Stitt's eye as a four-year letterman at wide receiver for Adams (Colo.) State, a Rocky Mountain Athletic Conference rival of Stitt's old program, Colorado School of Mines.
After graduating from Adams in 2013 with a degree in human performance and physical education, Hall spent the past two years as a graduate assistant for his hometown Colorado Buffaloes, working with the linebackers and defensive line in Boulder, Colorado.
Montana marks his first full-time coaching position. He will also serve as UM's defensive quality control coach.
