Earlier this week, 49ers head coach Kyle Shanahan said he doesn't ask Brock Purdy to do too much on the field. That was an understatement. Shanahan doesn't allow Purdy to do what lots of other starting quarterbacks are asked to do.

San Francisco 49ers quarterback Brock Purdy will be tested in the coming weeks with the absence of key offensive weapons.

Brock Purdy has faced the Vikings twice in his career. In both games, he turned the ball over twice, led the 49ers to just 17 points and lost. Which means the Vikings have his number. On Thursday, Purdy was asked what makes the Vikings such a challenge.
