What happened: Stribling entered camp as San Francisco's No. 33 pick. Purdy credited the rookie's grasp of route depths, details and alignments during team drills.
Why it matters: That early command of the offense strengthens Stribling's case for immediate work in the receiver rotation. His rapport with Purdy will shape how quickly that role grows.
By the numbers: Stribling caught multiple passes on each of the first two days of camp.
What to watch: Padded practices will test whether the rookie can sustain his early separation and timing.
