One week after being released by the Cardinals, Adam Snyder is back for another stint with the 49ers. The San Francisco 49ers ideally would have kept Adam Snyder around as a backup last season. However, Snyder certainly strengthens the 49ers’ offensive line depth. Snyder left the 49ers for the Arizona Cardinals last offseason, but the Cardinals released him after selecting two guards in the 2013 draft. The NFC champion Niners already have a steady offensive line intact to protect quarterback Colin Kaepernick, so Snyder might be fighting for playing time in his return. Returning to the 49ers makes sense. The 49ers’ current starting right guard, Alex Boone, was a Pro Bowl alternate a season ago, so a change at that position would seem unlikely.
