PROS: During his career, Riley has constantly been a staple for the Army defense. Has played multiple positions and various alignments that's proven to be a move around piece that's fulfilled many different roles. Best element of his game are his ball skills and blitz value. Frequently utilized as a blitzer off of the edge on timely run blitzes, he's able to create tackle-for-loss situations. His ball skills have enabled him to impede throwing windows and the results speak for themselves. His 20 pass breakups (as of 11/15) are the tied for the second-best mark in program history. An added commodity as a defensive back is his tackling abilities. Highly consistent tackler that isn't afraid to stick his head in the fan and make tacklers.
CONS: Does have some limitations in space and in man coverage. Zone has been his calling card and a little mixture of man-to-man coverage. Hanging his hat or depending on him turning and running with targets isn't his area of expertise. Keeping his back to the LOS in zone and allowing him to roam near the line as an extra run defender is where his value will be seen the most.
