The Packers' only victory against the San Francisco 49ers in the Matt LaFleur era was last year when they beat coach Kyle Shanahan's injury-depleted team handily. Both teams are at full strength now and after a 1-1 start, the Packers could use a signature performance that shows they will be contenders in the NFC. Co-hosts Tom Silverstein and Ryan Wood break down the match-ups, assess injuries and try to figure out if defensive coordinator Joe Barry has what it takes to slow down Shanahan's offense in this nationally televised Sunday night game at Levi's Stadium.
