Most QB situations shaking out as expected

SANTA CLARA, Calif. -- Conventional wisdom is batting .667 and possibly 1.000 when it comes to NFC West quarterback races.

Colin Kaepernick has emerged as the clear-cut leader for the No. 2 role in San Francsico, coach Jim Harbaugh said Tuesday. Matt Flynn is leading the race for the No. 1 job in Seattle and will make his second start in two exhibition games.

The terrain is a bit trickier in Arizona, where Cardinals coach Ken Whisenhunt spent part of his media session addressing Adam Schefter's report for ESPN suggesting John Skelton was leading Kevin Kolb in the race to start for the Cardinals.

Whisenhunt said what he pretty much had to say, that the process has yet to play out. Neither quarterback in Arizona has made a strong move for the job. Skelton could be the favorite by default. And with three exhibition games remaining, the Cardinals have time.

I'm heading to Arizona for the close of Cardinals camp early next week. Looks like we'll have plenty to discuss at that time.

Arizona faces Oakland on Friday at University of Phoenix Stadium. The Raiders lost their exhibition opener to Dallas, 3-0. The Cowboys completed 15 of 27 passes for 165 yards with no touchdowns and one interception. That included 3-of-6 passing for 30 yards from Dallas starter Tony Romo.

The Cardinals' top two quarterbacks have not yet thrown a touchdown pass in the preseason. Rich Bartel has one.
