Kyle Shanahan was on KNBR Thursday night to discuss the San Francisco 49ers training camp, as well as how Jimmy Garoppolo is coming along in the offense, Deebo Samuel, and much more. Usually, when you talk Jimmy G, it’s about his rehab process. The hosts spun the conversation in a different direction. They asked Kid Shanahan what Garoppolo’s understanding of the offense was. On a scale of 1--which would mean you were just introduced to Jimmy G--or ten, which meant that Garoppolo understands the offense front and back in its entirety.
