QB Jimmy Garoppolo
There’s not a bigger key to the 49ers returning to the Super Bowl than Garoppolo. If he regresses from his strong 2019 season, they’ll be in some trouble. They’ll be in the running if he’s the same as he was a year ago. An improved Garoppolo could carry the 49ers though. He’ll likely be tasked with throwing more after getting an increased workload throughout the 2019 campaign. He’s not recovering from an ACL tear this offseason, so he should be able to hit the ground running in 2020. Whether Garoppolo is discernibly better will be fascinating to see in camp.
