Around the NFC West: June 21, 2013Good morning, NFC West.I wanted to pass along a link to Jeff Chadiha's column on the Seattle Seahawks-San Francisco 49ers rivalry in case you hadn't seen it.Rivalries have been pretty tame in the NFC West since divisional realignment in 2002. Rarely has the division featured more than one successful team at a time.The Seahawks and St. Louis Rams went back and forth across the 2003 and 2004 seasons, when both teams were 8-8 or better (both were 8-8 or better in 2006 as well).
