Quote:One more thing about Niners camp on Sunday: Anyone who watched practice understood why Jim Harbaugh chose Kaepernick over Alex Smith last November. In a half-hour span Kaepernick flicked five sizzling passes of 21 yards or more, right on target, throwing three of the receivers open in very tight coverage. With a needy receiver corps until Crabtree returns (and maybe longer), Kaepernick’s going to have to make the most of some fledgling receivers. From the looks of practice, one of the newbies, second-round tight end Vance McDonald from Rice, could get a very long look in the preseason.
