According to a report by ESPN, the 49ers are targeting Week 12 for Jimmy Garoppolo to make his first start. The Niners acquired Garoppolo on October 31 in exchange for a 2018 second-round draft pick, he has backed up C.J. Beathard in his first two games with the team.

Coach Kyle Shanahan told reporters after Sunday’s win that the rumors surrounding the former Patriots quarterback were incorrect. Jimmy G and fans will play the waiting game but sooner, rather than later, Tom Brady’s backup will get a start.

Garoppolo is part of an ever-growing list of Brady’s backups to leave New England. How have his former protégés performed once they leave Foxborough?

Note: Kevin O’Connell, Matt Gutierrez, Rohan Davey and Jim Miller all backed up Tom Brady but they never started a game for the Pats or any other team in the NFL.

With Bill Belichick’s coaching, Brady’s backups went 13-6 (68.4%) in New England but didn’t have the same success once they left town. Combined, the future Hall of Famer’s six backups have gone 59-87 (40.4%) in regular season games.

Against-the-spread, the former Patriots quarterbacks weren’t complete busts. Outside of New England these signal callers went 75-68-4 (52.4%) ATS.

We don’t know much about Jimmy Garoppolo. In two starts in 2016 he attempted 63 passes, and a total of 94 in three seasons with the Patriots. The 49ers new quarterback might be a star but history suggests Garoppolo will struggle away from Foxborough to win games. Few teams are as well coached or talented as the Patriots.

San Francisco is hoping Garoppolo is the exception to the rule.
