San Francisco 49ers quarterback Brock Purdy is still making quite an impact in the state of Iowa despite being three years removed from his playing days for the Cyclones.

In Purdy's last seven starts, he has won four games, lost three, thrown six touchdown passes and six interceptions, fumbled once and posted a passer rating of 87. That's about as average as it gets. And he's playing on the best team in football.

The 49ers QB became a better vocal leader this offseason. How will that help him overcome injuries to Deebo Samuel Sr. and Christian McCaffrey?

Adding to the complications, cornerback Charvarius Ward also missed practice, struggling with both a hamstring and a knee injury. Meanwhile, safety Talanoa Hufanga is nearing a return from ACL surgery, but the 49ers may have to rely on younger, less experienced players to fill critical roles during this tough stretch.
