Some players notes from CSN's Mike Maiocco:
QB Colin Kaepernick: He's been taking the first-team reps. His arm strength stands out on the field. So far, he looks pretty good. He had made some tremendous deep and intermediate throws. Some of his shorter passes have been off target and very difficult to catch because of the velocity with which he throws. All in all, a nice beginning for the rookie.
RB Anthony Dixon: The big, shifty back got the first-team reps during Frank Gore's absence. He looks a lot more polished than a year ago when he was the third running back at this time behind Gore and Glen Coffee.
WR Ronald Johnson: Perhaps the most-impressive looking of the wideouts in the early days of practice. He and Kaepernick have hooked up on some deep corner routes. He has also been working as the deep man on kickoff returns.
