1. Final QB impressions: Starter Colin Kaepernick, backup Colt McCoy and third quarterback B.J. Daniels combined for four touchdown passes without an interception. The group made a positive final impression overall, even though McCoy averaged just 3.7 yards per pass attempt while completing 8 of 15 attempts for 56 yards. Daniels, a seventh-round draft choice, tossed two scoring passes on only nine attempts and added a 36-yard run. He looks like a keeper. Veteran backup Seneca Wallace did not travel to San Diego and doesn't appear to have a future with the team.
2. Injury list: Backup offensive lineman Adam Snyder appeared to suffer a wrist or hand injury. Running back LaMichael James suffered a knee injury. The extent of those injuries was not immediately known.
3. The spectacular: The 49ers' receivers deserve credit for making their quarterbacks look good. Rookie Quinton Patton turned a short pass from Kaepernick into a 43-yard touchdown. Veteran Lavelle Hawkins produced a 45-yard touchdown after breaking a tackle and making defenders miss. He made the grab after the ball bounced off his body high into the air. The 49ers also got spectacular plays from outside linebacker Cam Johnson. Johnson made a strong case for a roster spot. He had two sacks and also blocked a punt and recovered it for a touchdown.
