1. Final QB impressions. The 49ers already named Colt McCoy as their No. 2 quarterback behind starter Colin Kaepernick. The team also released Scott Tolzien, further paring down any competition at the position. This game should provide rookie seventh-round choice B.J. Daniels another opportunity to show he belongs in the team's plans as a developmental player. The 49ers haven't drafted and developed a late-round quarterback successfully since ... when? Daniels, Nate Davis, Cody Pickett and Ken Dorsey were the only ones San Francisco selected in the final three rounds over the past decade. Meanwhile, veteran Seneca Wallace should get a chance to leave a positive impression. The team could keep him in mind as a veteran fallback should a need arise in the future.
2. Injury list. The 49ers will surely limit or eliminate reps for some key players as the preseason wraps up. Some key depth players will be logging considerable playing time. Can the 49ers get out of this game without losing one of them to a significant injury? By my count, the 49ers lead the NFL with seven players on the reserve/physically unable to perform (PUP) and reserve/non-football injury (NFI) lists: Marcus Lattimore, Mario Manningham, Michael Crabtree, Luke Marquardt, Quinton Dial, Tank Carradine and Eric Wright. No more injuries, please.
3. The spectacular. This is the catch-all category for players who appear to significantly help or hurt their chances through big plays or big gaffes. We'll be watching for them.
