Originally posted by NinerBuff:Vernon Davis also split time during individual periods. The veteran play-maker began the day with the tight ends, but later ran routes with the wide receiver group.A.J. Jenkins appears to be much more comfortable. The second-year wide receiver looks fluid in his routes and is able to catch passes away from his body all over the field.Kaepernick's arm strength is still impressive as ever. Accuracy has also improved for the quarterback heading into his third NFL season. Kaepernick finished the 7-on-7 and team periods 9-of-15 with a dropped pass. Kaepernick's two-minute drive to close out practice ended on a 3rd-and-5 incompletion intended for wide receiver Chad Hall.
