The Seattle Times Seahawks on Cooper Kupp

From the article

Kupp praised Lock's performance despite the backup quarterback's lack of preparation reps with the starting offense. Kupp stated: "He did a phenomenal job. He took basically no reps with any of the guys that were out there all week, and you see the onus that he puts on himself to be ready when time comes." This suggests confidence in the Seahawks' offensive weapons and their ability to execute with Lock at quarterback.
