SANTA CLARA — Is Jimmy Garoppolo’s five-game sample size last December enough for 49ers opponents to calibrate into this season’s scouting reports?
“I don’t know, honestly,” Minnesota Vikings coach Mike Zimmer said on a Wednesday media conference call.
The Vikings, last year’s NFC runner-up, open the season Sunday by hosting the 49ers, who went 5-0 last season upon Garoppolo’s ascension to the starting role.
“Obviously he played well in all those games,” Zimmer said.
