XTRA910 audio: NFC West Week 15

Mike Jurecki and I discussed the NFC West's emerging identity as a division with strong and/or improving defenses in San Francisco, Seattle and Arizona. The division also features physical starting running backs in every city.

Our weekly Friday discussion on XTRA910 Sports 910 AM also touched on the Monday night game between the 49ers and Pittsburgh Steelers, and where the Cardinals stand with Kevin Kolb.
