#78 November 13, 1983 Dean Sacks Six
The Niners sacked Dave Wilson 9 times and picked him off twice, a half dozen of those sacks, still a 49ers record and, at that point, an NFL record, went to Fred Dean. The Niners went to 7-4 in a season where they'd ultimately lose the NFC Championship, beating the Saints here, 27-0.
#77 is tomorrow
