ESPN Insider material on Humphrey:

Kiper's blurb from his big board:
Quote
14. Marlon Humphrey, CB, Alabama
Previous rank: NR | Watch highlights
A hamstring injury slowed down Humphrey toward the end of the 2016 season, but he's an outstanding prospect with the physical traits of a lockdown corner. He ran a 4.41 40 at the combine at 6-0, 197. Humphrey had three interceptions as a redshirt freshman in 2015 and was a key playmaker for the national champs, and he had two interceptions in 2016, and the first was returned for a touchdown. Humphrey has great bloodlines, too: His father, Bobby, was a big-time running back at Alabama who was picked by the Broncos in the first round of the 1989 supplemental draft.
