Sunday was no banner day for NFL quarterbacks.

Of the 22 teams in action, 14 managed fewer than 20 completions. Nine were in the low-to-mid teens. Three were south of 50% in completion rate, while three others were fractionally over. Even with the tepid performances, combined with a half-dozen squads enjoying byes, there was movement in our latest QB rankings — notably one significant leap.

For the moment, let's focus on one who kicked back Sunday after a dynamite game three days earlier.

Dallas had not trailed in five previous home outings. The Cowboys' average victory margin was 29 points. Suddenly, Dan Prescott was staring at a fourth-quarter deficit. No problem. He helped produce three scores in the closing 11:30 for a six-point win over Seattle.

Prescott pitched three touchdown passes with nary an interception. He ended a yard shy of 300 while stretching a streak of two-TD passing games to six with 20 during the streak.

The news Sunday that the Cowboys are working on a contract extension comes as no surprise.
