Brock Purdy signed a five-year extension worth $265 million two weeks ago to make him one of the highest-paid quarterbacks in the league. The big contract comes with higher expectations, especially since the 49ers lost eight starters this offseason as they prepared to make room for extensions to Purdy (and Fred Warner and George Kittle).

Following the big deal getting done between the 49ers and Purdy, head coach Kyle Shanahan has spoken out about what he wants to see from his quarterback.

A book excerpt from Michael Silver reveals how quickly Mike Shanahan — father of Kyle Shanahan — was sold on Purdy.
