Amari Cooper becomes Raiders' best-ever rookie receiver

Cooper, the fourth overall pick in the draft, broke the Raiders' record for most receiving yards by a first-year player (771) that was set by James Jett in 1993.

Cooper will leave Jett -- and plenty of other standout Raiders wideouts -- in his dust. In 1998, Hall of Fame wideout Tim Brown had 725 yards on 43 catches as a rookie. Cooper is on pace to beat that mark by several hundred yards. Let that sink in.
