It's not surprising that strength is the first thing Air Force football coach Troy Calhoun is asking for in the process of leaving behind the worst record in the academy's 57-year history. The Falcons finished 2-10 overall (0-7 Mountain West) last fall and began spring practice Wednesday trying to begin the road back to winning seasons. "We will be a stronger team physically," Calhoun said. "I've been extraordinarily pleased with what we've done in the weight room. Our players have attacked the weight training, and it's a jump-start for us." Calhoun and his staff will be working with maybe the most players with game experience of any of his previous six spring practices. At the end of the 2013 season, only one senior was starting on the defensive unit. "We'll have more strength, more power, but it still has to translate to the playing field," Calhoun said. "It's invaluable to have a good number of older players. We can compete. But before you really can walk, sometimes you stumble and hit your nose." A lot of work will be focused on the quarterback position this spring. The Falcons had four quarterbacks start games last fall, and only two will be available for heavy duty this spring. Junior-to-be Karson Roberts and upcoming sophomore Nate Romine will share the majority of the work. Sophomore-to-be Pate Davis is in the mix; senior-to-be Kale Pierson, who made one start a year ago, is recovering from knee surgery; and Jaleel Awini has left the academy.
