But as far as actual experience, he will take the field Sunday against Washington as a starter for only the 16th time in his career.By most measures, Garoppolos return to action this season after missing the final 13 games of 2018 with a torn ACL has been a success. The 49ers are 5-0, atop the NFC West, and Garoppolo has taken every snap of the season.
