49ers observations: De’Zhaun Stribling stars in preseason opener

Key Points:

• The 49ers rested their regular starters during their preseason opener against the Tennessee Titans, with coach Kyle Shanahan focusing on evaluating younger players and roster hopefuls due to his ongoing concussion recovery.
• Rookie wide receiver De’Zhaun Stribling impressed in his preseason debut, catching seven passes for 63 yards and making several notable plays, indicating he could have a significant role alongside veterans Mike Evans and Deebo Samuel.
• Quarterback Kurtis Rourke showed promise before leaving with a rib injury, completing 12 of 14 passes for 101 yards and leading a touchdown drive; he is viewed as a potential backup quarterback for the future.
• Defensive rookies Gracen Halton and Jaden Dugger took advantage of playing time, demonstrating disruptive and physical skills that could earn them more significant roles alongside established linebackers in the regular season.
