Indianapolis Colts linebacker Darius Leonard has gone from a relatively unknown player to the NFL's rookie of the year.
Some questioned why the Colts selected Leonard, who played at South Carolina State, a Football Championship Subdivision school, in the second round of the draft.
It didn't take long to realize why the Colts liked Leonard so much. He dropped into coverage and showed off his athleticism by going up to intercept Andrew Luck's first pass during training camp.
