One of the biggest storylines going into the 2015 was replacing longtime starters at quarterback like Marcus Mariota, Brett Hundley and Sean Mannion so all eyes were on new Pac-12 quarterbacks in week one.
Based on what saw in the first week of play, here is how the new starting Pac-12 quarterbacks played in their debuts.
1. Josh Rosen Fr. UCLA (34-16 win over Virginia) 28-35 351 yards 3 TDs
Rosen had one of the greatest QB debuts in Pac-12 history and not just for a true freshman.
