It's time to look at the top-performing Pac-12 quarterbacks after the fourth week of the season. We'll revisit this ranking each Tuesday. Expect some variation here with each edition, as we'll be judging every individual game performance more heavily than the full season of work:
1. Steven Montez, Colorado: Montez lit up his first career start -- on the road and in a vaunted stadium, no less -- and led his team to a program-defining victory. The Buffs' 41-38 win over Oregon was a monumental step in their resurgence under Mike MacIntyre, and Montez made history while leading them there with 333 passing yards and 135 rushing yards.
