Kiper's analysis: "Solid TD-INT ratio, but his 56.5 completion percentage is 83rd nationally. Arm and intangibles there, but stock slipping."
Stanford quarterback Andrew Luck, a redshirt sophomore, remains in the No. 1 overall spot.
Luck and Locker will go head-to-head on Saturday in Husky Stadium.
It wasn't a good week for other Pac-10 players. UCLA linebacker Akeem Ayers fell from 12th to 15th and Bruins safety Rahim Moore was knocked off the board after rating 22nd last week.
The Bruins just lost 60-13 at Oregon.
