The brother of former San Francisco 49ers quarterback Jimmy Garoppolo was not impressed on Thursday by Kyle Shanahan's coaching during the Niners' 12-6

Not everyone, though, is willing to grade on a curve. Including Billy Garoppolo, brother of Jimmy, who offered some comentary about Niners coach Kyle Shanahan on Instagram on Thursday night. "Offensive Guru," Garoppolo joked with the aide of several crying laughing emojis.

Almost two full seasons after Jimmy Garoppolo’s underwhelming tenure with the 49ers came to an unceremonious end, the quarterback’s brother reveled in San Francisco’s weather-challenged 12-6 loss to the Rams on Thursday night — with Jimmy backing up Los Angeles starter Matthew Stafford.
