SANTA CLARA — It was another opportunistic, rise-to-the-occasion performance by the San Francisco 49ers' defense against a top NFC opponent in the season opener.
Except for one thing.
"As a group, we weren't pleased with our tackling," coach Jim Harbaugh said. "It's not what we've been accustomed to the last couple of years with our defense."
The 49ers uncharacteristically missed several tackles in key situations, allowing the Green Bay Packers to turn short gains into big plays before San Francisco pulled out a 34-28 victory.
That's one area where the 49ers will look to get better entering Sunday night's showdown against a top NFC opponent that ran over and through the San Francisco defense the last time the divisional rivals met.
