Here are numerous videos posted by San Francisco 49ers reporter Cam Inman to the Youtube page of the Mercury News. The videos are from the 49ers' OTA practice this past Friday, including one that we posted yesterday.

They include looks at quarterback Colin Kaepernick and his new throwing mechanics as well as various drills for the defensive backs, running backs, wide receivers and linebackers.
