Around the NFC West: May 7, 2013The San Francisco 49ers ideally would have kept Adam Snyder around as a backup last season.The alternative wound up being even better.Snyder's departure to the Arizona Cardinals last offseason contributed to San Francisco netting three compensatory draft choices in 2013. It also cleared the way for Snyder's replacement in the lineup at right guard, Alex Boone, to develop into a long-term starter.Then, after the Cardinals released Snyder last week, the 49ers re-signed the versatile veteran to a two-year deal worth much less than Snyder received from Arizona.
