The 49ers have finished up their second round of informal player workouts led by quarterback Alex Smith. After organizing two separate four-day mini-camps at San Jose State that included most of the team's offensive players, Smith said he has installed about as much of new coach Jim Harbaugh's West Coast system as he can this summer. "I know what I installed and everything I basically threw at the wall. I don't know how much of it stuck to the wall," said Smith, a free agent expected to re-sign with the team. "And I think that's going to be the test when these guys come back, whenever this thing ends, how much of it stuck."
