During pre-practice warmups he lined up at running back. He was also among a handful of players fielding punts at the end of practices.
In between, B.J. Daniels took snaps at quarterback, the position at which the 49ers selected him with their first of three seventh-round picks in last month's draft.
The 49ers have already asked Daniels to do a lot of different things on the practice field. And that's just fine with him. His versatility is perhaps the biggest attribute Daniels has on his side as he completes against Scott Tolzien, the No. 3 quarterback the past two seasons, for a spot on the 49ers' roster.
"Whatever's asked of me to do, that's what I'm going to do," Daniels said.
Daniels' athleticism was apparent during the 49ers' three-day rookie camp, which concluded on Sunday. Generously listed at 5 foot 11, Daniels is not built like a prototypical NFL quarterback. And that's fine because the 49ers do not view him as a prototypical NFL quarterback.
At 217 pounds, Daniels looks more like a running back. So that is why the 49ers want him to learn the footwork of a running back and also, perhaps, help on special teams. He also looked comfortable catching punts, a skill on which he has been working since playing his final game at South Florida.
"I'm comfortable with my hands," he said.
Daniels demonstrated a strong arm and on two occasions during Saturday's practice, blasted out of the pocket to produce big plays with his legs in the non-padded, non-contact drills. On the sideline observing the drills: 49ers quarterback Colin Kaepernick. Daniels is well-versed in running the read option.
Daniels will attend all quarterback meetings as he competes for a roster spot. It's through the quarterback's eyes that he can learn other positions, too. The 49ers are also likely to eventually consider him at wide receiver, too.
"The quarterback has to know everything," Daniels said. "That's one of the most important things, and that's what I'm trying to do right now.
"Right now I'm just trying to make sure I know how to tie my shoes and walk correctly. That's the biggest adjustment for me right now."
