The San Francisco 49ers are facing significant pressure in the upcoming season, particularly on their second-year players. With a strategic decision to limit spending in free agency, the spotlight now shifts to young talents like Ricky Pearsall, who is expected to step up into a starting receiver role following Deebo Samuel's trade. Cornerback Renardo Green will also need to elevate his performance after becoming a starting CB due to roster changes, while safety Malik Mustapha's progress is crucial for a stable secondary. Running back Isaac Guerendo must prove he can handle a larger role behind Christian McCaffrey, and linebacker Tatum Bethune may see increased responsibilities as the team navigates its evolving lineup.
