With the 2017 preseason Defensive Player of the Year Dorance Armstrong off to the NFL a year early, Kansas will be missing a huge piece of its defense. The good news, however, is that Daniel Wise will be back, so KU will have at least one known quantity on the line.
Cause for Concern
This was just mentioned - with Armstrong gone, who will step up? KU has a lot of unknown at defensive end. And when KU goes to four down linemen, whoever will be lining up next to Wise is also a bit of a mystery.
