Buffs secondary
A look at the Colorado secondary during spring football
Cornerbacks
Chidobe Awuzie, 6-0, 205, Sr.: One of the top defensive players in the Pac-12, he started at nickel back last year but is now working strictly at corner. He had 90 tackles, four sacks, two interceptions and 10 pass breakups last season.
Isaiah Oliver, 6-1, 185, So.: As a true freshman, he played 216 defensive snaps over nine games, getting most of his time late in the season. Has tremendous upside.
Ahkello Witherspoon, 6-3, 190, Sr.
