4. Darius Kilgo, DL

The rookie sixth round pick went from roster hopeful to key backup in a matter of four weeks. Kilgo, a former Maryland star, fell in the draft due to inconsistency, but was picked in the first place because of the flashes of brilliance he showed as a Terrapin.

With the Broncos this preseason, he was out-performed (if you want to call it that) only by teammate Shaquil Barrett, who was the best defensive player in the NFL this preseason arguably. Kilgo was phenomenal in his own right, showing off his ability to anchor as well as penetrate. He will play a number of positions on the D-line for the Broncos and could see a ton of action early in his career.
