Former San Francisco 49ers quarterback Sam Darnold reflected on his one-year tenure with the organization. Now the starting quarterback for the Seattle Seahawks, the 28-year-old credits his year with the 49ers for propelling his career forward.

For the 49ers their health has become a greater concern than their preseason performance. They just need to make sure they have enough healthy bodies to keep their key starters out of harm's way. More than 20 players missed their preseason opener vs. the Denver Broncos with injuries, and that number could rise Saturday when they face the Raiders.
