The careers of Jimmy Garoppolo and Brock Osweiler, both with small sample sizes of game play before signing massive contracts, couldn't be more different. After helping the Broncos go 5-2 during his time as the team's starter during its run to Super Bowl 50, Osweiler was average -- at best -- in Houston. He's jumped around since his short stint with the Texans and is currently a backup in Miami. Jimmy, on the other hand, has flourished with his new team, recording a 5-0 record last year as a starter under Kyle Shanahan. Garoppolo instantly changed the feel of the season for a 49ers team that didn't get its first win until Week 10. This is a prove-it season for him. Can he continue to win?
