The 49ers' training camp can be defined by one variation of a play that developed repeatedly. Vernon Davis lining up exclusively at tight end utilized his straight-line speed to blow past a linebacker in the middle of the field. Then quarterback Colin Kaepernick with laser-like precision beamed a 25-yard pass between the safeties 25 yards or more down the field. That scene took place on the practice field more than a dozen times during the 16 practices that were open to the media this summer. And it figures to show up regularly once the real games begin too. The 49ers per NFL rules were obligated to have their practices open to the media through the first two exhibition games. Coach Jim Harbaugh's practices for the remainder of the season will be closed. Thus the outside observation of 49ers training camp has come to a conclusion.
