MOSCOW, Idaho – All week, Idaho head football coach Paul Petrino had seen progress. His dueling quarterbacks, Matt Linehan and Chad Chalich, were getting better. On Wednesday morning, in fact, they shared snaps during what Petrino said “might have been the best practice we’ve had since I’ve been here.” But then Saturday morning happened. Chalich and Linehan both threw two interceptions and posted similar numbers in the second scrimmage of fall camp to further cloud the starting quarterback race.
